Deff the head.
Honestly though, I don't think the difference is in the Revision really. I had a Rev G blackface head and a Rev G Racktifier and the head destroyed the Racktifier, even with the same exact tubes in it. I even had an FJA modded Racktifier a few months later, and that thing sounded like ass compared to the Rev G head and Rev F head I had at the time.
I've always heard the Racktifiers are the same thing, just in a rack enclosure, but that's certainly not been the case with the ones I've owned/tried.
