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.
NeoVim is almost a drop-in replacement for Vim (the configuration file is under .config). Plugin installation might be different, tho.
Find a migration guide and be brave.
