I have both GB Premium and AMH and I would pick AMH without hesitation. I have had AMH for over 3 years now and I still play it regularly. I also still hear new callouts, some of which are genuinely comic gold. The playfield on AMH may be somewhat less refined than a modern Stern, but it's fun to shoot and the rules are top notch. GB may be more of a looker, but it would take a monster code update on GB to close the gap. The scarcity of AMH and the production issues with GB can't be overlooked either. Either game will require more dialing in than average to get it to play right.
