Iv been running CentOS 3.3 - 3.4 with cpanel for long time
i use to use RHE as well, i personaly dont see any differnce
between the 2 except centos is free
I must admit that I've never been a hugd FreeBSD fan, but mostly out of ignorance. Built a server for cPanel a short while ago and got it all up and running with little fuss and a bit of help from Google
Although a little unfriendly, FreeBSD is one of the best OSs, especially the latest release. This is not to mention the fact that FreeBSD is, relatively speaking, the most secure OS. It is personal preference.
