Whereas Ubuntu 8.04 Server Edition (or 6.10, 7.10, 8.04.1 for that matter), would not install on my Compaq DL 380 G2, Debian 4.0 will.
I have installed Debian 4.0 flawlessly via CD (both via full CD install and the smaller net install) onto two DL 380's with duplicate hardware/firmware. And since Ubuntu is built off of Debian, it's pretty easy to get used to if you're already very comfortable with working in Ubuntu.
Just to throw this out there...
