If you're getting MOR, trip sixes, and LITZ 6 times in one game you might want to compete, or set up your game and rules a bit tougher.
As for the Games in this thread, I'd put them MB/Munsters/GB
I've owned GB and have MB currently. GB Premium is beautiful to look at but shooting it just isn't fun. The scoleri bros targets are a freaking insult with how cheap, and the right ramp might as well not even be there it's so tough to hit. The Pro is a bit nicer to shoot but on either game the ball flys all over the freaking place and you combine that with the flipper gap it's about as fun as getting a colonoscopy.
Munsters while I haven't played too much on, at least shoots like a decent fun game and the theme is well integrated.
MB on the other hand nails everything from shots to flow to theme, but of course there will be those that say it's too easy - you can absolutely make it more difficult.
