Best praise vs top criticism for OnePlus Watch 3

WearOS offers a lot as it really makes the watch into a tiny smartphone. But it has its costs to offer that. A simpler OS (as Tizen was) is really more suited for these relatively small devices with (compared to full smartphones) tiny tiny batteries - for obvious physics reasons with current battery tech. That is why the OnePlus watch 3/2 solution of offering dual boot is so smart an idea. Work with a more primitive but much leaner OS normally AND offer you the option to boot into WearOS when you need the fancy stuff. Or the other way round: Use with WearOS when frequent charging is not a problem, and boot into the leaner OS when you prefer prolonged stamina. IMHO **all** fancy smartwatches *ought* to have the option to dumb down so it was never more power-hungry than needed for the user's selected active features.

Unfortunately none of the werOS watches offer a reasonable battery life. The least bad is the 46mm variant of the oneplus watch 3, as it offers to boot into an OS more suited a smart watch, while not an strictly need of fancy WearOS features (the model 2 does offer dual boot as well as do the 43mm variant watch 3 with a lesse bettery)

Check out the Amazfit T-Rex 3, Balance and the Active 2 as well as the BIP 6. All really good devices. I'm using an Active 2 myself

Go away from T-Rex 3 right now. Amazfit released T-Rex 3 Pro and all the software goes for T-Rex 3 Pro. and metrics of T-Rex 3 (readiness crap and sleeping) are pretty terrible so if you want Amazfit go for T-Rex 3 Pro or Balance 2 or GT 5 Pro but not T-Rex 3.
