For me the Bally/Williams games are awesome. I like the design of those machines and how they play. Of course most stern games have more complex rules, but i just don't like how they feel to play. For me the B/W games feel more solid than any stern. The sterns feel too hard and rattly, toy-ish. I have an AC/DC which i like because of the rules and complexity, but don't like too much because of how the pinball feels. Won't buy any more Sterns and hope for good PPS remakes which feel like B/W
