I upgraded from a series 4 and yes for me it’s a game changer. But in hindsight I would have returned it and just gotten the ultra 1 used. The new gesture feature is not that useful, in fact I never have a reason to use it. There’s never been a scenario that I cant interact with the watch and have to use the double tap gesture. It’s quite useless tbh, and limited. I would not upgrade from ultra 1 fur sure
