BR isn't even in the discussion, cool cannon toy but a repeat-center-shot shallow ruleset.
JMn is also an unbalanced ruleset, with the Spinner Millions/4x/Hold Bonus method, but what a package! It's got great flow, an amazing toy, great head-to-head strategy on that matrix (locking on the best rewards, squatting, starting tic-tac-toe multi, etc), and one of the absolute coolest final modes ever. A very cool machine! Someone posted once they had replaced the JMn spinner with an older Bally spinner or something and it really balanced the scoring out.
JD is your typical mode based gameplay, but great art, dots, sound effects and certain modes are actually very cool. Dead World is a neat toy with the mod. The shots are so unique and different, this is a cool pin to have in a big lineup. But the shots are a little off, and the sweet shot from the right flipper is the post for the left ramp... it's not as kinetically immersive because of how clunky the shots are laid out (that's why it was a dud on location, but players grow to love it in their homes as they grow accustomed to the off-beat shots).
It's close between JD and JMn. JMn is definitely the better player, with the best toy, but there's something to be said of JD's uniqueness, awesome art and dots...esp if you have several fan layouts in your collection.
