I gave a more detailed description in another response but I've tested and felt both and the S22U just feels and looks like hell to me. The body is absolutely horrible and too big (my S9+ with a chonky case is the same size as it without a case). Also, S pen isn't my thing.
Imo, samsung is just copying Apple's design inspiration and apparently their business ideas now. The other S22s other than the ultra are kinda cool but I want the Space Zoom, among other things.
Just take a look at the S21U in Phantom Silver vs the S22U Phantom White
