My favourite that I use lots of places is Gnome. Love using it. Use it completely stock.
I also use KDE, which is fine, but I don’t much care for it, I always find it to be buggy and unreliable. Could well be pebkac errors, but I’ve seen it across multiple machines over the years. With this said I still use kde on one machine.
I also use sway. Which is a wayland window manager. I find it very good. I’ve heard that hyprland is also good, but I’m not looking to mess with a window manager, I just like it to be simple, so I’ve not really tried it.
