Cobbler - what is the advantage?

Hi guys, new user here, so please be gentle.

I need to build a lot of servers at work on a weekly basis with various versions of RH and additional applications.

We use PXE/Kickstart to do this with selections made from a simple menu structure.

However, I keep hearing about Cobbler and although I have some documentation on it, I still cannot figure out any advantage it has over the pxe/kickstart method.

What am I not 'getting'?
