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 had to write my shortcuts for i3, so I didn’t changed them, I just wrote what made sense, e.g. super+f for full-screen. Most of them are the “default” ones that the example configuration uses, but that’s because they’re sane defaults.
