Ahhh, the linux distro wars bitciontalk style.

IMO debian and unbutu and the projects based on them such as mint are the most supported though the community with a lot of places to look for help.
CentOS and it's forks tend to be more stable (not always but tend to be)
And FreeBSD is a royal pain in the ass, but once you get it up it's rock solid and secure.

But, for something like this. If you install one and it does not work for you, just move to the next. You don't have to live with any particular distro if it's not working the way you want it to.
