We like Debian for all the usual reasons. apt-get is close to magic. Don't trot out RH's autoupdate thing. I've heard of it.
You do get apt-get for RH, though (http://apt.freshrpms.net). Works quite well too. I use it on one of my home boxes (the other runs Woody) and manage to keep my distro updated reasonably well.
OTOH, one of the support guys tried to install Debian on a box with RAID, and can't get it to work. It works fine with RH.
Which kind of RAID? Using a regular RAID controller with SCSI, or IDE hardware RAID (Promise/ Highpoint) or software RAID? I'm guessing that this might be the IDE RAID thing, for which the RH default kernels provide compiled in support. Don't know about Debian, but maybe they don't have it.
Cheers,
