I find it very easy to install and use. Drivers work fine out of the box. The window and desktop management is my favorite ever, so it stays on the home desktop. There are a few things like flatpaks from the cosmic store not always working properly, and you need to remove them and install stuff from deb packages instead. And I couldn’t get any clipboard manager app to work, I think that’s related to a more general wayland issue, but nevertheless frustrating.
