KISS is better. better layout, better rules.

Aero is a better band but who cares really.

There's a reason why Stern employees - among them some of the top pinball players in the entire world - have chosen KISS as their game of choice to trade high scores on. It's a great game to play, great game to compete on. The right amount of code, easy to understand, difficult to master, with lots of cool little tricks in the code for getting big scores.

I liked Aero a lot when it came out but it got old fast, there's just not much to it and you get tired of playing that same multiball over and over. The mini wiz mode is a big let down and the main one is impossible to get. I don't know anybody who has beaten Elevator multiball. And Aero LE is another clumsy half-baked premium model with cumbersome "features" crowbarred in to satisfy the big spending crowd. Kiss pro is where it's at.
