Open Stack

I would like to get some feedback on which OS to choose for OpenStack
Host OS, CentOS 6.4 or Ubuntu 12.04. Just from technical point of
view, e.g.

- Ease of deploy

- Support of new features

- Performance benchmarks

- Community support

- Number of bugs

etc.

My impression so far is that Ubuntu is more up to date with the
support of OpenStack, it has newer kernel and packages. For examples,
like Python version. Ubuntu also seems has more community support etc.
But at the same time, Redhat is rank as one of contributors to the
OpenStack code base.

Any input or comment will be welcomed and appreciated

Thanks
