I have to set up a server that should be as secure as possible. Which security enhancement would you use and why, SELinux, AppArmor or grsecurity? Can you give me some tips, hints, pros/cons for those three?

AFAIK:

SELinux: most powerful but most complex
AppArmor: simpler configuration / management than SELinux
grsecurity: simple configuration due to auto training, more features than just access control
