I tried a huge "wraparound" dell screen and after 3 months I never got used to turning my head: I kept centering a window that was roughly 4:3 aspect ratio, just enough to fit 80 columns of text and a sidebar in VSCode/Sublime, or a typical browser session.
The biggest problem I had was switching between laptop screen and giant monitor. It sucked, I would constantly have to fix the desktop whenever I went to a conference room and returned to my desk.
I think if you work in exactly one desk, and simply need auxilliary screens that you don't look at frequently, big monitor or multi-monitor helps, but I don't know what situation would call for that when you can just swipe to a new desktop.
