It's great, but of course, it's alpha. The most horrible thing about it for now for me, it's XWayland compatibility (horrible gaming experience for now for games using Proton). I even created my issue about it. But the snappiness, tiling, customizability ow god... it's so great. But many things are not yet properly optimized, like the screenshot utility creates a big screenshot sizes.
I will probably create a list that are great and that should be improved as feedback for System76.
Yeah summarizing - shit happens but I still love it. For Wayland supported applications the experience is absolutely gorgeous. I play now Factorio that has Wayland and non-locking saves.
