both are currently priced about the same (400 ish dollars) with the s23FE on sale for black friday , I am trying to go back to samsung after getting tired of the pixel 6A but I am on a budget , it looks like the S21 ultra is better in almost every way on paper but the S23FE is much newer so im struggling to decide , if it helps any the samsung S10+ is my favorite phone of all time i only switched to pixel when it broke
S23fe newer plus my opinion don’t like curved screen prefer flat ones.
Unpopular opinion from me but i actually loved the curved screens, the S10+ had a massive curve that made the phone feel super sleek and advanced and i loved the feel , it was very comfortable. the only downside for me was that its much more fragile
