You cannot go back after trying it :D.
Ultrawide screen for life.
(i've been a 29 ultra wide + 24" user. Then I changed for a standalone ultrawide 34". Since december I changed for a standalone ultrawide 49". And it's like a dream for me.)
I did! Used to have a Samsung 49" ultrawide. After using it for a couple of years, I sold it and got a 16:10 32" QHD, which I found worked better for me (+ one or two laptop screens for chat / random stuff when I'm doing serious work).
The biggest issue I had with the ultrawide is that most of the games that I played weren't optimised for it, especially in some games where things like the mini-map might be at the far end of the screen, or worse, if it was an older game then you'd have to put up with black bars, or play the game in windowed mode.
I do game, but I do not always game on all the screen. It depends on the game and the focus I want.
For example, e-sport, I use 2/3 of screen to game, 1/3 of screen for browsing and discord.
For solo gaming or a game needing focus, I play fullscreen.
league of legends works really well in 32:9 ! But I use it in 21:9 (2/3 of my screen), which already is an ultrawide ratio.
Civ 6, Baldur's gate 3, witcher 3, work well in 32:9 (using the full screen). No worries here. Humankind too.
For some, there are adaptations but it works too. Skyrim or fallout for example. There is a software named "flawless widescreen" ; it improves the experience for initially poorly compatible games.
I do use a software for windows layouts with macros. Meaning I can switch the disposition of my browser, explorer, discord, signal, pdf or anything and my games depending on what I want to do. And that, is really enjoyable.
In my personal experience most games either work fine out of the box or after some tweaking, I've had a 49 inch 5120x1440 monitor for almost 4 years now. At times you'll need to use Flawless Widescreen or Widescreen Fixer to get things working, or UI mods if the game supports that. But worst case you can always try a better supported widescreen ratio or 16:9 and live with some black bars, not ideal, but not the end of the world either.
