I run a mix of Centos and Debian.  If you setup your system correctly 
you aren't going to get hammered.  It's all down to what apps you are 
running.  SeLinux helps but I find it gets in the way.  If SeLinux where 
the panacea it's being billed as here then more distros would have it 
enabled by default...however the opposite is true.  Contrary to the 
apparent belief on this list it IS possible to properly harden a box 
without SeLinux.
