My girlfriend is very happy with VA4s, it has good sleep tracking, lots of sports activities and also the Ox sensor. While not 100% reliable, the 4 can track HR while swimming, while the 3 cannot. The 4 will also do respiration rate and body battery.

My almost-3-year-old FitBit versa died today, and rather than just replacing it with the Versa 3, I'm considering a switch to another brand - probably Garmin, based on my research so far. I swim, cycle and walk, all of which I like to track as I do them, which is possible on both of these options. The Garmin Vivoactive 5 comes in at a competitive price point of $300/€300/£260. This makes it an attractive option for those looking for a feature-packed smartwatch without breaking the bank. On the other hand, the Samsung Galaxy Watch 6 is priced similarly, with the 40mm model starting at $299.99 in the US, £289 in the UK, and AU$549 in bxGAiGO.
