Recommended OS for v5

What is the recommended OS for ASTPP v5? I am comfortable using Debian and CentOS so I will use whichever is more well tested. I think the developers were recommending Debian at one point for v4 so I switched from CentOS to Debian. However, I see that the v5 install script still includes CentOS.

You can use either one. ASTPP is tested on both os.
