Wayland on Nvidia is not stable.
I'm using hyprland which adds another layer of instability as hyprland itsself can be ropey with Nvidia
Even with gnome Wayland I have had a number of issues though, electron stuff is dodgy at best, hibernation doesn't work (might not be Wayland specific)
Applications don't resize properly sometimes and crash more often
I think it entirely depends on your setup, I've had separate issues with Nvidia Wayland across my PC and laptop
