I use Limo, it takes some getting used to after using Mod Organizer 2 for so long but it gets the job done. I havent used it for any huge modlists yet though as it tends to be a little buggy/unintuitive sometimes.
There’s also a way to get MO2 on linux, should he on github as modorganizer2-linux-installer.
For desktop use debian sucks. I dont want to wait a year to update my apps. For servers its fine. Arch and Nix are my favorite rn and im looking to convert my home media server into Nix soon.
