Depends. If they're the same price and condition, I would take JackBot. It's the more interesting game, and worth more. I like the game enough that, even though mine has been a headache and a half, I'm still intent on making it work. (I got a basket case. They're mostly not that bad, and were designed intentionally to be easy to work on for operators.) Breakshot was designed to be inexpensive; Capcoms are generally reliable from what I hear, but the number of people able to help you if something goes wrong will be smaller than the number of people that can help with a WPC game like JackBot.

This is true. The eye holes on the ones with colored inserts at the top row don't cup the balls properly. The ones with white inserts there play much better.
