dwight does some super coding as well. to me, the best 2 newer sterns the past few years are still ghostbusters pro and game of thrones pro. twd pro loaded with Lyman code and interesting unique shots as well. im not sure kiss or AS rivals either of those 3. haven't played batman 66 so cant comment.

(quoted from above. my disputes in parenthesis below)

There's unique, and then there's poor design!

Giant flipper gap = poor design (cftbl has this and people seem to accept it)
Droopy flippers = poor design (you can raise them if need be)
All the catapult of death airballs = poor design (happens on many games and you can change rubber on certain posts to adjust that)
Inlane-to-outlane hops of death = poor design (there is a clear plastic on ebay that fixes this. it goes over the entire area on both sides and works fantastic. i put them on all of my ghostbusters and it fixes that issue, btw metallica and bbh and avatar also do this).
Balls not smoothly returning from left orbits, ricocheting slightly & going STDM = poor design (its pinball). if you hit the side of cabinet to maek the ball avoid the left sling and use skill you can drop catch it on the let flipper or let balls do a dead flipper bounce to a cradle on rt flipper pending speed.
Balls exiting pops and usually going STDM = poor design (acdc, avatar, gb, kiss, aerosmith, twd all do this) there are ways to get around that too.
Balls shooting out of saucer STDM = poor design (saucer strength can be adjusted in the menu. i adjusted mine so they kick out balls to the left flipper, they basically drop straight down to an easy cradle.) you can also change saucer kickout strength)
Slimer always being broken on location = poor design (stern will send out new slimers for the problematic ones on the earlier releases to cure this).
Prem/LE right ramp often stopping the ball halfway up, then sending it back = poor design (agree) pends how much the legs on back are jacked up though)
Modes as linear ladders = poor design (thats a code thing)

Unique doesn't = good if it plays like shit. Wanna play a GOOD unique layout!? Try Wheel of Fortune! Nordman did something super unique with that game, and despite it's incomplete code, it's a fantastic playing original non-fan game!
