Ritchie and Lawlor have made some of my favorite games so I'm not going to compare them as both are excellent at they're particular style of machine.
BK and Wonka are both great themes to me.
Looking forward to playing Wonka more than I am BK as there is more to explore.
From the videos I've seen I don't care for the way the upper playfield on the premium shoots. The pro looks like another good Ritchie fan layout.
