@[email protected] enjoy and/or good luck! If it helps in any way; I recently switched from Fedora (Silverblue, GNOME) to Debian and am using and thoroughly enjoying Niri too.
Since I'm also using the unfortunately named Dank Material Shell, installation for both ended up being super simple on Debian by using Dank's installer and repositories, so I don't even have to use that other package manager thing Niri suggests for Debian, which means I also don't have to compile half the internet just to get my new favorite DE π
.
This way I get the stability and boringness (meant only in the good ways! π) of Debian, while I get to enjoy Niri too!
Though sadly I still don't get ZFS on root this way, something Cachy will be able to give you. I really wish there was an option to have Debian with ZFS this way without having to go through super convoluted installation shenanigans. C'est la vie.
Anyway, enjoy! I hope it'll work out for you. But if it doesn't or you simply miss Debian, know that using Dank's repositories is a nice way to get there too! π
