For me, I really want to get into niri, but the lack of XWayland support scares me (I know there’s solutions, but I don’t understand them yet).
Also, I stopped using Emacs (even though I love its design and philosophy with my whole heart) because it’s very slow, even as a daemon.
I've been using niri lately and couldn't believe so many apps wouldn't launch. I didn't know that was the issue. I had been manually editing so many desktop entries to make them work...
