Linux comparison poll

I like Linux, but after trying several distros, I thought it would be good to ask what other distros people have used for Blending.
So far I have found;
Ubuntu; easy to use, good performance, but Blender and other items are a bit out-of-date.
Sabayon/Gentoo; Easy install, good performance, applications intall from source. can be tricky to work with.
Puppy linux; Great distro for its size, but not the easiest to modify, and 32 bit only.
