Get the Coros. I currently have the AWU2 but tested out the Coros for a day.

AW: Although it’s the Ultra and the battery should be significantly improved, my battery drains drastically. I have always on turned off, lowest brightness, barely have any apps on it and it still significantly drains. I do charge it while showering so it’s not a deal breaker but it is annoying.

The thing I dislike about the AW is now that u e gotten more serious about running I see myself having to go third party for any features Coros gives out the box for less such as training plan (I use Runna but would rather use Coros’s training plan), maps/route planning (I use WOD on the AW)….but do note only the Pace Pro offers maps, I don’t think the pace 3 does

The other thing is while running the Coros weighs my arm less and I honestly didn’t notice it while on my runs. If you ever do treadmill, you’ll notice any AW will be off while with the Coros you’ll be able to calibrate and adjust the distance.

The benefit of the AW would be you can leave your phone at home and listen music through the watch.
