And as a third choice - don't get either, save up some money and see if there is another cool theme that is coming out in the next year that people will jump on and be the NBT (Next Big Thing).
Comes down to budget, game play and what do you really want? I love these threads because it boils down to what is your choice and personal preference.
I already have a Godzilla Premium and am in the category if I had more cash and space would try to be in the "both" category if I could . Also agree with the money in IRA post above in the thread .
If torn equally between the machines - buy neither and hold out for another theme you REALLY want. Pinball machines are like casinos on the Las Vegas strip. There is always another shiny cool one just down the street. Good luck with whatever you decide.
