They both look fine. It doesn't matter to me. My phone will always be in a case.
I prefer the S21; however, what I; or any one else this late in the game prefers is meaningless to Samsung. Therefore, if I, or anyone else, wants an S22 ultra they will learn to live with the five little separate bumps, or move on to another phone.
from the renders...I would go with the S22 Ultra hands down!! I mean a flush camera is the best solution. Mo more wobble on a flat surface. Not to mention the pure aesthetics of it.
