Ubuntu - because I can find answers for just about any problem easily. In the past we started with Redhat then Centos, that was back in the day of more simple RPM where you had to resolve dependencies manually. We were mainly using the unit as an internal LAMP and file server, nothing exotic. After Ubuntu went into creating server versions we went that route. The on-line community was way more active and the package manager just worked. Ubuntu is definitely a route of lower frustration when things go wrong.
