I had an Apple Watch for a couple of years when they first came out. Personally, I didn't find it all that beneficial since I carry my phone everywhere, and most of the time it was just a glorified notification shade.
Hooked on nice mechanical watches now and don't think I could or would want to go back.
As for using a non-Apple watch with an iPhone, my understanding is that key features like sending messages don't work, which feels like your giving up a lot of the reasons you might be considering a smart watch in the first place.
