I'm curious as to the advantages of using Debian over Ubuntu on the server - is it considered generally more stable or better debugged? This is something I've never explored and am interested in your thoughts about it.
At some point in the future, I'd like to give OpenBSD a try.
Debian stable moves very slow, which makes it an excellent base OS for a server since predictability dictates that your app brings with it whatever that it needs to run.
For example, nodejs on debian would be outdated, which would force you to setup your app to use a specific version of nodejs that you want to use.
