Today, I would plan on using Ubuntu 10.10. There are packages, specific (well-tested) documentation and almost all the core developers seem to be using it. Grab the ppa dailies on launchpad or install from source with the contrib/novascript.
If you can't use that, the next in line would be RHEL 6. There are packages for it but only a few people on #openstack are using.
I would avoid CentOS until they release CentOS 6. As CentOS 5.5 is still python 2.4 based, you will run into a myriad of dependency issue. I've gone down this path and it is littered with pain.
