For this one thing, they may work the same... Overally though, ubutnut sucks... Use Debian.

With no doubt, Debian is the best OS.

Things like Ubuntu are Debian's children, with a layer/layers of crap on them, which sometimes make them totally different.

Fedora and Ubuntu are out there, so that Red Hat and Debian would get better... So I suggest you don't use them at all.

I saw something about SELinux... Actually, I'm using that too... Those are things you can add to any distro which has a new kernel. But you can't change the basic architecture of a distro.
