I own a SW Premium and love it! Lots of risk vs. reward in running the shot multiplier up and then shooting strategically to cash in.
I've played a JP LE on route a bunch and it's ... okay. Not a big fan of the theme, but the T-Rex is cool. If I bought one, I'd definitely get at least a Premium.
Ghostbusters? Blech. Not in love with the theme (like many others seem to be) and have found it to be frustrating to play.
