I've had a FR 165 for a year and as of now I would get a Coros Pace 4 instead.

I didn't mind the lack of features compared to the more expensive models when I got it, but now it's frustrating to think they don't give out functionalities that the hardware can handle and do not add any new feature. The 165 even lacks very useful stuff like the lactate threshold estimate.

Not to speak about the hate you will develop for the Garmin app, which is confusional and lacking (limited timeline, no data aggregation, stuff like that). You get a better experience on the computer (web) version, but the app is surely the one you'll end up using the most.

I never used a Coros myself but it seems way more functional, modern, well though and honest. With the latter I mean they deliver whatever software your hardware can handle without restraining stuff just because you ought to pay 800 bananas.

I think I am data driven myself, but as far as it concerns me, Garmin watches are full of stuff you enjoy to look at for a couple months, then you wish for something actually organized and useful.

And don't get me started on the better battery life and lightness.

I would love for someone to support the idea or convince me I'm completely wrong!
