Garmin
Forerunner 255 Series
Long battery; but wrist HR tracking is inconsistent.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
My VA4 seems to do a great job.
I just bought it a few days ago, and have been loving it so far! Upgraded from Vivoactive 4
I have Ignite 3 and Garmin vivioactive 4. Garmin is much more accurate. Ignite 3 at the distance 1200m is loosing 150m. In both cases there is no problem with Strava.
I'll stick with my Garmin Vivoactive 4
nope, apple watches will tell you things like "well done, your a legend" for moving. my garmin vioactive 4 told me a few moments after a half marathon that it was "time get up and move"
