Oracle Enterprise Linux, Ubuntu Linux, and more Linux

So I've been building a few Virtual Machines using Oracle VM as well as VMWare using different distros of Linux to see the major fuss between them all. Seems everyone has a favorite.

At least from an Install point of view, Ubuntu was easily smoother, however OEL offered many more installation and configuring options to start right away. This I liked. I have to be honest, I could care less how pretty and customizable Ubntu seems to be if OEL can run Oracle software better in any way. I'll keep posting anything that I find to be a deal breaker for me. I am just looking for the best of breed to build out my many testbeds for all the configurations of the Oracle stack I'll need. I am sure many of you out there are in the same boat!
