Quoted from ryanwanger:But I'm really a Pro snob. I'm more about gameplay than toys, and Premium/LE toys generally slow things down. They're more about show than flow.
I feel the same way in most cases. I value game speed over just about everything. However, I find that Ghostbusters is the one game that the Premium has sped up gameplay considerably. The right entry to the ramp on the Pro does the thing where it just sort of slows and then returns, where the right ramp on the Prem is a quick return. The ball lock subway was a surprise to me because on the pro, the ball bounces around a decent amount before registering the switch.
I haven't played enough of Black Knight Premium to know if I prefer it, but it feels weird without an upper playfield in it. Having said that, I don't like any of the Black Knight games before it thanks to the upper playfields, so I might like the Pro more ultimately too.
