what was the best shooting mechanism for 2016?

[Amit3339]

During the build season we had a discussion about our way to shoot the boulders into the high goal. The main two mechanisms were(of course) a catapult and a wheeled shooter. Throughout the season I've seen some amazing teams that used both methods and reached an amazing consistency, but somehow I always thought that the catapult is much more consistent because it didn't had nothing to do with the condition of the boulder.
I was wondering if someone on CD have some data about the type of shooting mechanism that teams that were on Einstein had?
I would be happy to hear what other people think? was the catapult more effective or was it the wheeled shooter?
