I like Slackware. But I'm lazy, and I reverted to apt-get for stability and to save time - I took a Kanotix HD install, removed all the Kanotix bits, and gradually stripped it down to only what I use. At least that way I had a system that worked right away and could get some work done while tinkering.
Anyway I wish you luck
- I used to have lots of problems with 3D in Ubuntu - probably too much patching going on. I reckon simpler is better!
