Based on administering some 15 or so servers at work, I'd full-heartedly recommend Ubuntu Server. We started out with CentOS but are now (slowly) migrating to Ubuntu Server. Ubuntu has a wider selection of more up-to-date packages and lots of handy helpers (like tasksel and other config wizards) that will make your life a lot easier. For anyone who suggests that Ubuntu is for desktops, not servers, remember that the Wikimedia Foundation runs Wikipedia exclusively on Ubuntu servers.
