I would actually comment that System 80 and 80B allows for a more diverse collection than System 11s.
With those Gottliebs, you get some early System 80 stuff that feels like System 1 (which in turn feels like it could practically be EM.) and you get some semi-modern masterpieces like TX Sector, and games that almost feel like early DMDs. Hell, some of those games feel more evolved than some Gottlieb DMDs.
Because of the change over to Premier ownership, it's almost like you've got two different companies that you're considering one.
