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.
i3, or Sway if you’re on Wayland, just gets out of your way.
Have a virtual desktop for each use case, memorize where your apps are, and enjoy muscle-memory-based window management. Mod4+1 brings me to terminal, 2 is browser, 3 is work stuff, 4 is personal chat, 5 is email… Every app is fullscreen, for maximum screen real estate. Nothing annoys by blinking when I’m trying to concentrate on something else.
