Ubuntu has a more stable schedule of LTS that is 2 years apart but Debian is only "roughly" 2 years which makes it easier to plan when to make the upgrades. Also stuff like having root disabled and letting normal users use sudo by default and having had unattended-upgrades that does automatic security update installed by default makes you feel there's actually someone who cares doing the QA. And it has great number of packages along with PPA in case there isn't one pretty much allows you to handle most software without manual compile/install/update process which is a nightmare from admin perspective to do. And the fact it had worked great on me over the last 10 years against 100 or so servers makes me feel confident using it.
