I will take your word on that particular comparison ...
What sold me was when I needed to build a new kernel to add support for
On Centos: A nightmare (not that there is anything wrong with Centos,
its just what Redhat does to the kernel build is enough to make a grown
hacker cry), can't easily generate rpms for it. Make rpm sort of does a
generic RPM without really packaging up headers, sources, module links,

insert a modern up-to-date kernel into the .spec is an exercise in masochism
On SuSE it is even worse.
For all intents and purposes, if you need to deviate far from the
supplied kernel version, you are basically toast unless you do *lots* of
things by hand. This makes things like Fedora look nice as they build
the modern kernels for you, albeit not necessarily with the options you
With Ubuntu (Debian for all intensive porpoises) you pull your kernel
source, make changes, patch what you need/want, build your config (all
of which you have to do on the others anyway to make sure it will build
