Quoted from luvthatapex2:None. You are limiting yourself if you are looking at just 4 titles of thousands to choose from. I wouldn't want any of those 4 if i could only have 1 machine. There are way better machines. Look some more, go to a show, play some friends games. You also didn't mention budget. If i had 1k vs 5k the choice would be very different.
Great point - what's your budget? Maybe that doesn't matter since you listed out those specific pins. But if not, I'd really do some homework and find a pin with a shot layout, rule set, artwork and theme that you really like. I like to look at my pins about as much as I like playing them.
Personally for me it'd be T2. T2 was the first pin I ever bought and it's still in my collection. I'm hoping one of these days one of these software wizards will add some more depth to the rule set and this pin could go from a B level pin to a highly demanded A pin...
