There is something I am interested in, which Linux distribution do you prefer to use?

I also would like to know the differences, because I honestly don't know the background differences between the different distros.

So far, I have only used Kubuntu, Debian, and Knoppix. I have a personal tendency to drift towards the KDE environment.

I've spent most of my time using Kubuntu, only installing Debian on desktops that I use as data storage until recently when I got a new laptop. I haven't played with Debian too much on my laptop because I have sound issues on it. As for Knoppix, I've only used the Live CDs for it for issues in Windows or partitioning issues.

Granted, I haven't even answered my own question...I guess the answer for now is Kubuntu. I think it'll probably change once I play with Debian a bit more.
