It’s not conventional wisdom, but I’m happiest with arch.
I’m familiar with it
can install basically any package without difficulty
also love that I never have a gigantic version upgrade to deal with. sure there might be some breaking change out of nowhere, but it’ll show up in my rss feeds and it hits all my computers at the same time so it’s not hard to deal with.
Arch never really surprises me because there’s nothing installed that didn’t choose to put there.
