I've had a handful of setups, a classic single monitor from 4:3, then 16:10, than 16:9 and now 21:9. I've added a second vertical monitor, two twin large vertical, main vertical, secondary horizontal... Well in the end I'm happy enough with a single 21:9 FLAT WQHD. Game devs might not like the aspect ratio, but with EXWM, Firefox with tab-center reborn, casual simple split view etc it's good enough.
I prefer avoid curved ones because they feel strange if we are not "at the right distance" and I like to be distant a bit and I use a standing desk with a magnetic treadmill for the standing part so my distance vary, but the real conclusion is: a good monitor is a LARGE one. Rotation does not matter much if the overall dimensions are large enough.
