Final Thoughts
Pick the Apple Watch Series 9 (9.6/10) if you own an iPhone and want the most polished, all-around smart-watch experience. Strengths: top-tier health sensors, seamless iPhone integration, very bright display, fast performance. Ideal for: iPhone users who want best-in-class apps, notifications, and a feature-rich health stack.
Choose the Garmin Venu 3 (9.3/10) if accuracy and multi-day battery life matter most. Strengths: highly accurate wrist-based metrics, reliable GPS, long runtime, strong fitness insights and animated workouts. Ideal for: serious athletes and long-duration tracking where battery and measurement consistency are priorities.
If you need a lower-cost alternative with great runtime, consider the Fitbit Charge 6 as a practical backup — but for the clearest split between smart features and pure fitness performance, Apple Watch Series 9 and Garmin Venu 3 are the top two picks.

I’m tempted by the Fitbit Sense 2 for stress and sleep features — the guided tools and ECG sound perfect for someone who’s been trying to manage anxiety. BUT I keep hearing about the paid subscription for advanced insights.
Is Fitbit Premium absolutely necessary to make Sense 2 worth it, or do the built-in features give good value without paying monthly?
I used Sense 2 without Premium for 6 months and liked the core features. Ended up subscribing because I wanted the sleep coaching — the tips actually helped me normalize my sleep schedule.
Also worth checking for promo trials — sometimes Fitbit includes trial Premium periods with new device purchases.
If you’re mainly after ECG and stress detection, you’ll be fine without Premium. Premium just makes the data prettier and more actionable imo.
The Sense 2’s hardware provides ECG, SpO2, and basic stress tracking out of the box. Fitbit Premium unlocks deeper trend analysis, sleep coaching, and some advanced metrics. You can get good value without Premium, but if you want coaching and long-term trends, the subscription adds a lot.
Fitbit Charge 6 for value seems tempting — 6 months Premium included is a nice bonus. I’m mostly using it for runs and strength training and want decent GPS and heart rate during gym equipment sessions.
Does Charge 6 reliably read HR on ellipticals/treadmills where the watch isn’t moving much? And how does it compare to Versa 4 for daily readiness?
Charge 6 generally performs well on steady-state cardio and gym equipment; it also has the feature “Heart Rate on Exercise Equipment” which streams HR to compatible machines. For Daily Readiness, Versa 4 and Charge 6 are similar, but Versa 4 gives a slightly fuller smartwatch experience (notifications, apps).
If streaming HR to gym equipment is critical, double-check compatibility of your gym machines with Fitbit — some brands integrate better than others.
Don’t forget battery — Charge 6 lasts longer between charges than Versa 4 in my experience.
I use Charge 6 on the treadmill and it’s been stable. The strap fit matters — snug but not choking. Also the Charge is slimmer so it’s less awkward during lifts.
If you want the best mix of value and features, Charge 6 is hard to beat. Versa 4 is better if you want that smartwatch feel and more on-wrist control.
Amazfit Bip 5 seems like a steal for battery life (11 days!). I’m not looking for a fancy smartwatch, just reliable HR and decent GPS for weekend runs.
Has anyone tracked distance with Bip 5 for 10k runs? How accurate is the HR and GPS compared to phone + chest strap? I’m cool with budget accuracy, just curious.
One tip: update firmware right away — GPS and HR accuracy improved for me after an update.
I used Bip 3 for several 10k runs and it was within ~100-200m vs my phone GPS in most cases. For budget gear, that’s acceptable. HR was good for zone training but not perfect on sprints.
Amazfit Bip 5 is solid for the price. GPS is decent for casual runs but can wander a bit in wooded or urban canyon areas. HR is fine for steady runs; for max-effort intervals, chest straps remain more accurate. For weekend runs and multi-day battery, it’s an excellent low-cost pick.
If you want long battery and don’t obsess over 1–2% accuracy, the Bip line is perfect. Also, customizable faces are a nice bonus 😄
I’m training for triathlons and trying to pick one device to rule them all. Looking at Garmin Venu 3 for accuracy and the Samsung/Apple options for features. Any recs for triathlon use — tri-friendly, durable, and great GPS?
For triathlon I’d favor Garmin (especially models focused on multisport), and while the Venu 3 is great, some triathletes prefer Garmin’s Forerunner or Fenix/Enduro lines for multisport features and mapping. Samsung and Apple are fine but are less triathlon-focused in terms of transitions and multisport recording.
Agreed — Garmin Forerunner/Fenix are the go-to for tri. Venu 3 works if you want a nicer display and battery, but Forerunner 955/265 or Fenix for ruggedness are tops.
Garmin Venu 3 sounds like the accuracy + battery combo I need. Anyone compare the heart-rate accuracy during interval sprints vs a chest strap? I do short, intense workouts and sometimes wrist OHR feels laggy.
Garmin’s optical sensors are among the best for wrist-based HR, and the Venu 3 tends to track intervals better than most. That said, chest straps still outperform wrist sensors for very high-intensity, rapid cadence changes. If you need absolute precision during sprints, use a chest strap; for everyday tracking the Venu 3 is excellent.
I do sprint intervals and paired my Venu 2 with a chest strap for a week. The Venu 2 was close but sometimes lagged on the peak spikes. Expect slightly smoother curves with a chest strap, but Venu 3 should be an improvement.
I’ve been eyeing the Apple Watch Series 9 (renewed) listed here — I love how tightly it integrates with my iPhone, and the display sounds gorgeous. Battery life being “good but not class-leading” is my only worry since I’m not thrilled about charging every day.
Has anyone bought a renewed Series 9 from Amazon recently? Any issues with battery degradation or cosmetic wear? Also curious if the health sensors on renewed units perform identically to new ones.
Renewed units can be a great value. On Amazon, most renewed sellers grade cosmetic condition and often replace batteries if capacity is below a threshold. I’d check the seller return policy and warranty length. Sensor performance is usually the same unless the device had prior water damage — rare, but ask the seller specifics before buying.
I bought a renewed Series 9 for my partner — zero issues so far. If you’re worried, check that it’s sold by Amazon Renewed or a top-rated refurb seller. Also, make sure it’s unlocked/paired back to factory before you accept delivery. 👍
I picked up a renewed Series 8 last year and it was basically perfect — slight scuff on the underside, but battery life was as expected. If you get it, run a few heart-rate checks against another device in the first week to feel confident.
Samsung Galaxy Watch 6 Classic (renewed) looks slick but “moderate battery life” = nope for me. I don’t want to babysit charging every night. Plus renewed units make me nervous 🤨.
If battery life is a top priority, the Venu 3 or the Amazfit Bip 5 will serve you better. The Galaxy Watch 6 Classic has great features and the rotating bezel is lovely, but expect daily charging with heavy use.
Agreed. I had a Galaxy Active and loved the bezel, but battery was meh. Sold it for a Garmin and haven’t looked back (for multi-day use).
Versa 4’s Daily Readiness is pretty legit — helps me decide if I should rest or crush another workout.
But I’m wondering how it stacks up against Garmin’s recovery metrics. Garmin seems more ‘serious athlete’ and Fitbit more ‘everyday helpful’. Anyone tried both? Also — typing this with half my coffee gone, so take that with a grain of salt 😂
Tried both — Garmin for marathon training, Fitbit for daily maintenance. Garmin gave deeper numbers; Fitbit told me to chill and actually helped me stop overtraining.
That’s a fair summary. Garmin’s recovery tools (like Training Status, HRV-based insights) are geared more toward performance athletes and require more contextual data (VO2, training load). Fitbit’s Daily Readiness is simpler and more accessible for everyday users. Your choice depends on whether you want deep training analytics (Garmin) or straightforward guidance (Fitbit).
Garmin’s ecosystem is better if you pair it with third-party analytics platforms. Fitbit feels more “in-app” focused.
