Default [Q] Functionally, how different is GPe from AOSP?

I've been on CM for a while, but I'm thinking of switching to one of the GPe 4.4 ROMs. I'm under the impression that GPe is just an AOSP "skin" running on Sense. With that said, how different is it from AOSP? Are the settings the same? Do hardware buttons work the same way?

Screenshots of pertinent UI would be appreciated!
