It's not really about space for me. I have enough room for 2 monitors but don't because I like having a minimal space (my desk is just a single monitor, small lamp, and 2 small figures with cables hidden).
I've tried ultra wide and didn't really like it and ended up returning it (I kept he monitor for almost the entire 30 day return period to try to get used to it). I also play pretty equally between consoles and PC and ultrawides are useless on the console front.
