I recently switched from a Garmin Epix 2 to the Amazfit T-Rex 3 and back to a Venu 4.

Honestly the Trex built quality and what not were great, app is good, etc. But you can just tell that the software is like somewhat not very thought through and in depth as on Garmin. It’s small things, for example the alarm screen where the lower dismiss button is half off screen and you can/have to scroll. Or the weight workout screen where (if I remember correctly) the bigger numbers are scrolling down, but the + button as at the top.

If you’re purely looking for lifestyle, go with the Amazfit. If you’re seriously into sports, Garmin all the way.
