Niri is so good. I've switched to using it about 5 months ago and it was legit the best computing decision I can remember making in recent history to move away from Windows.

I have a huge amount of gratitude towards the author of niri.

My dotfiles have always included an install script for setting everything up around command line tools, theme switching and more but it fully supports niri now too on Arch based distros https://github.com/nickjj/dotfiles in case anyone is shopping around for a new desktop environment and wants to get going quickly. I run it on both my main desktop and a travel laptop.
