I have a Fenix 2 that I've used for running, cycling, weight lifting, hiking, etc for years. The only thing I don't like is that it's huge (imo) for everyday use, so I don't wear it daily. I briefly used it for phone notifications, but stopped. I really like Garmin products, and definitely recommend them.
I recently got a 2nd gen Apple watch through a deal at work, as part of our wellness program, where it was subsidized to $50. I wouldn't have paid full price for it. If I hadn't had this available, I'd have gotten the new Fenix instead, as I've been looking for an upgrade for a few months (wanted one with wrist HR monitoring). I'm not sure yet if I'll actually get any meaningful use from the Apple features - so far, I've sent 2 stupid canned responses to texts because I have fat fingers, so I'll probably not use that function any more. Tried to use a golf tracker yesterday, but the watch features require a premium subscription, which I'm not going to do. Looked cool, though.
