Currently, Arch btw. I was on Ubuntu in the 12* days, but arch wiki had the solutions to every problem I encountered, so naturally migrated. I want to switch to NixOS but ran into some issues getting my finicky nvidia/amdgpu laptop to work. I might go blendOS as a holdover, it seems like a good mix of the two. Also I have some issues with Manjaro (tried for a while) but pamac cli at least handles all of my aur and pacman needs properly.
