Old thread... lots of killer observations made so I won't retread except to say that I like both AAB and replay games depending upon the ruleset and artwork.
In general, for me, most AAB's have crappier artwork and last too long. As Boatcat mentioned, the fundamental geometry of most EM's favor the game time and risk of a 5-ball game... so AAB's rarely win out for me.
And now the opinions...
I like Klondike over Yukon (too easy).
2001 (better art) over Dimension (way too easy). Even though 2001 can be modded to reset the drops, I don't do it. Makes rolling the score especially challenging which is more fun.
Flipper Fair/Subway over Cross Town (the replay is the adaptation in this case and is too difficult... the geometry and huge flipper gap begs for AAB rules).
Playball (better art) over Home Run (too easy).
Royal Guard (better art) over Palace Guard (too easy).
Spanish Eyes in AAB mode (difficult to earn, short ball times). WHY did they bother installing ball-in-play lights up to 10? NO ONE can earn that! Even getting to 7 seems impossible.
Paradise (far better artwork) over Pleasure Island.
Ice Revue (better layout) over Ice Show.
Doozie (better layout) over Daffie.
Card Trix (better rules) over Flip-A-Card (aside from specials no real reason to aim for anything at all!).
Captain Card over High Hand (blech).
King Pin (better art) over Pin-Up (too easy).
Would like to confirm Diamond Jack vs. King of Diamonds and Ship Ahoy vs. Buccaneer.
