All of my virtual servers are on Centos 5.5. Now I am deploying new one and there is a new OS option: CentOS 6. I like new software, and I prefer to use new versions (but not the edge). So, as far as I am not an administrator and my apps are not highloaded is it a good choice to prefer CentOS 6 to CentOS 5.5?

In my opinion, no. CentOS 6 is very much behind RHEL 6.1 and Scientific Linux 6.1. See:

The problem here is that the upstream distribution has moved on, so CentOS 6 isn't really a good target platform. I would wait until CentOS 6.1 is available or stick with 5.x.

Edit: One option for CentOS 6 is to leverage the continuous release repository (CR), which keeps the CentOS 6 point release in sync with RHEL 6.1. It's a slight compromise, but would be another option for continuing to use CentOS.

Even 5.x is falling behind. RHEL 5.7 has been out since Jul 21st, and as of today, still no CentOS 5.7. – Chad Feller Sep 5 '11 at 16:14
@Chadd, that is not true: [root@centos /]# cat /etc/redhat-release CentOS release 5.7 (Final) – Rilindo Dec 3 '11 at 20:44

Certainly you should test things, but CentOS 6 is essentially RHEL 6, and RHEL 6 has been in serious production for almost 10 months now (CentOS was slow in getting organized for RHEL 6 for whatever reason).
