Honestly, I can't remember the last time I had Debian stable go wrong in any application[server,desktop,laptops or raspian]. I use it everywhere and it is pretty fantastic.

Despite Debian being phenomenal in many ways, it doesn't offer up a head for the chopping block to replace yours if things go wrong in a corporate application. Good luck getting IT folks to deploy anything that doesn't offer them an out.

Using CentOS knowing that it is downstream from RedHat but that RedHat would step up and fix things in a semi-timely manner was good enough for many enterprises....at least until IBM got involved.

Ubuntu is also a weird choice generally speaking because Ubuntu just uses Debian's testing repo as a base and really only significantly varies in the kernels that they roll for various products/services.[cloud,live patching,etc.] They used to maintain their own desktop[Unity] and service management[upstart] and a bunch more variances from Debian...but that ain't really the case today.
