Well i agree with you guys centOS 6 is by far the best .rpm distro i've try, And i do love his GNOME monastic UI .
From the .deb side i was a big fan of Ubuntu 10.04 LTS but Ubuntu choose to follow an other path now, so from the .deb side CrunchBang is now my First choice by far.
Then .rpm or .deb is a vast debate. From How Debian is Made its harder to do a more stable system. I never had issue with Ubuntu or CrunchBang. I do agree that some install can be tricky but i also remember crying on installing Maya and Renderman on a Fedora ...
So i wouldn't say that Debian is less Stable than a red hat ! it will be harder to configure ... Sure !
, but when all is setup correctly it will never fail ... (well in theory ...
Again you can find big companies on Debian base Distro like weta or buf and good company on centOS like ILM. But again i wouldn't say one is more stable over the other.
Well ... To me (as a dangerous Debian Integrist
) i will definitly say that you can't find a more stable OS on this planet than Debian ...
(But this is where is loose all my objectivity ... )
