I had the Ultra 1 and I hated it.
Quit sticking your head in the sand. The sum total of what you’re saying is basically “I don’t believe the speed improvements are significant” . I have both, and the Ultra 2 is more than 30% faster in many areas. There are more bottlenecks than CPU speed which have been fixed.
Dude, I am not arguing that it isn't a better watch, of course it is. But no one else anywhere, in this this very thread, even reviewers that usually just praise whatever Apple does, is claiming improvements like you are. I bought my wife a Series 9, and have tried it a bit, haven't felt anything significant different.
And by the way, I buy a lot of stuff just because I feel like and usually don't feel any need to justify - I ended up upgrading from an iPhone 14 Pro Max to an iPhone 15 Pro Max and the experience is pretty much the same but what the heck I'm happy with my purchase. I also own both a Surface Pro 8 and an iPad Pro 2022, PS5 and Xbox Series X, etc, you name it. So the point I was trying to make is I'm not really someone who justifies my decision to buy or not tech,
Good you're seeing improvements meaningful to you, but I do think some of your claims are quite exaggerated.
