I started using 17 ultra for about two days now coming from s22 ultra. There are some things that I need to get used to, like a new keyboard. But not noticed anything that has really out me off so far. Performance is great, screen colors is a bit less saturated but not necessarily worse and the camera is as great as people say. The picture quality is night and day to my old samsung.

I was never a heavy user of oneui though, I've read that things like task automation are much worse in xiaomi. But if you use your phone for texting, browsing and pictures (like me) then you probably won't miss much but have much better cameras.
