Quoted from Doctor6:I'd say the premium is the smallest upgrade that stern has done in a long time.
The premium was my first pin. In hindsight I might have gone with the pro and used the saved money towards an older game, but I'm a big Maiden fan and I REALLY prefer the cabinet art on the premium.
Seems I was luckier than most since my autoplunge works 100%, but I've had to loosen the sarchophagus post to get hits to register, the manual plunger seems a bit off, and the flippers sometimes feel a bit weak.
