I know someone who uses an ultrawide monitor and been playing games at their place a few times, and it's pretty amazing. The only downside is that not every game supports it or even runs well in it. You don't have to twist your neck, it's just you don't have to look around with the camera to see more stuff if you want to, you can just peek, and see stuff coming off the side of your view without needing to fully focus on it.
It's a 10/10 experience, one of those things you have to try to know how good it is.
