I've never really played much with Mageia since the live USB never wants to run right on either of my computers. I don't know if it's because I use unetbootin to write the iso or what, but the liveUSB never seems to run right, so it's very hard for me to try out Mageia.

So I can't really comment on it, but have heard it's an excellent alternative to debian-based and ubuntu-based distros
