Despite apt being a piece of shit sometimes, debian is relatively stable without very many breaking updates to configuration files. I prefer to use it for servers (including vms) simply because of that.

believe it or not i've never used debian
i don't think i have a favorite but i am currently using opensuse, and i at least don't dislike it

I've only ever run SteamOS sorry

the "debian lesbians" meme

It just works for average use
Although I really am starting to prefer fedora for non-server use
