Yeah, asking which distro is the best is kinda like asking what color is the best. It's all based on personal preferences, what I like isn't necessarily what others like (and I KNOW what I like goes gainst the grain). Best thing you can do is try out several and see what YOU like.

Personally, my favorite is Slackware. I've tried the others, but always went back... If you want to know my reasons, I can write a disertation on the various distros, likes and dislikes about them, as well as other happenings (like the LSB)
