A lot of my customers use Ubuntu on their production servers, but I don't really understand why. You're getting the latest stuff, but there's no guarantee that it all works reliably. They invariably come across problems such as imagemagick crashing (on an earlier version of ubuntu), or avconv using up all your memory when converting some ogv files to mp4 (current bug on 14.04), plus a bunch of others. I always use CentOS on my servers, and have been very happy with it. It's rock solid. I haven't even upgraded to CentOS 7 yet. I just moved to a new server in March and decided to stick with CentOS 6 until systemd becomes a bit more stable.
