So what would people's opinions be on running this vs. Ubuntu LTS on a server? What about one that relies on more recent features (LXC et al)?
Ubuntu has a stronger desktop community when you run into problems (largely due to scale), but debian has a strong server community. And the Debian Way of doing things usually stays the same way for years for a given subsystem - google providing advice from 2009 is likely to still be helpful. The ubuntu philosophy... not so much. A colleague wanted to turn off thin scrollbars in the ubuntu desktop, and found that for the last four 6-mo releases, there were four separate ways to do this...
But, on the other hand, ubuntu LTS is better supported by a lot of vendors (eg AWS has an official ubuntu AMI, but no Debian one). It depends on your use case, I guess.
