I ended up here looking for current recommendations for switches as well. I just finished replacing a GE ZW4005. It just went poof & disappeared out of SmartThings. As it was out in my shop a ways away re-adding is pretty iffy. I grabbed a used one out of a box (I vaguely recall pulling it because it has some issues a while back) paired it at my desk, then installed it. The bad one that started things seems to be working fine at my desk when I re-paired it. So ya, had some weird issues with GE as well that i’ve never had with my Levitons.
One thing I REALLY like about the GE’s that I didn’t think of when getting my original GE & Leviton switches… The GE’s are push up for on & push down for off. The Levitons are push (down is the only option) to toggle state. It’s surprisingly annoying to have a toggle rather than the traditional on/off paddle style.
