I have owned GBLE, TWD pro and played a good few games on AS. I loved TWD especially with the wire fence mod. Loved it so much I sold it to get an LE or Premium. Then when I played the premium it was so much worse. I have wanted a pro back ever since and it is the only game I regret selling ever.
GBLE I just sold and can't recommend you stay away from it enough. StAY AWAY if you are looking for a keeper pin. Code is not good and it has been confirmed it is likely done for good. I took a loss of $1000 selling it and couldn't be happier it is gone.
AS is a lot of fun. Fast, good flow and satisfying shots. However I don't know how polished the code is as I did not dig too deep in.
My vote would be TWD pro at a great price and then put the fence mod and maybe some other cool mods on it. Really fun game, challenging but rewarding and great code. Such a great theme. All around beauty and you don't need the premium as it plays worse... seriously it does.
