Personally, I would prefer Debian to Ubuntu-LTS on servers. The primary advantage of Ubuntu over Debian is access to more recent package versions, and LTS surrenders most of that advantage in an attempt to approach Debian's reliability. Besides, most use cases for servers don't require bleeding-edge packages as long as the distribution is backporting security fixes. I wouldn't worry about LXC support; it's fairly old tech by now, and even the previous stable version of Debian supports it. LXC in Wheezy should work just fine. The only major issue I can think of with putting servers on Debian is their very very old kernel versions. The kernel in Wheezy is missing a lot of recent optimizations in the networking and filesystem code, and doesn't support user namespaces (important for container-based virtualization).
