The idea of liking an operating system is kinda bizarre to me.
So far explaining why I like one has just been a case of whether or not it frustrate me. Fedora just failed me on that one. I don't love anything particular about Arch - it just never make me want to pull my hair out, and in the rare cases something fails, it is always possible to fix and I often learn something in the process. It is also hard for me to put my finger on why I dislike a distro - other than the process of using it causing me frustration.
Also I'd like to give a shout out to SparkyLinux - a small Debian distro that just works.
edit: ea. an operating system shouldn't be there for me to have opinions on it, it should sort of just melt away in the background without needing me to think about its existance.
