I think its a matter of personal preference.
Centos 7 works fine, Centos 6 also, and even centos 5
32 bit works fine and 64 works fine.
You might have a speed advantage on x64, but not really required since the memory used by a single Gameserver is not above 4gb.
Personally i use Centos6 x64 for both servers and never had any problems because of the OS
