Bit biased here as I own one but will say Ghostbusters premium / LE. Would also go with KISS premium / LE.

GB has an incredibly unique layout, it's the entire opposite of a fan layout seen in a majority of new pins. Artwork is incredible, as is the audio when you consider all of the custom music created for the individual modes as well as custom callouts by Ernie Hudson. GB is Stern's last DMD game and offers some of the best DMD animations to date. The number of toys, especially interactive toys and molds, packed into GB surpasses all other modern Stern's in my opinion. The biggest thing holding the game back is its code which sounds like will be completed this year with a massive update.
