Baxter was extremely fast but could be pushed around pretty easily.
I can also only speak for Curie..
I really liked 188's simple and effective design. There was one team that had an obvious "weapon" of a stacker mechanism, I can't remember the team number anymore, but I know they flipped us and busted our electronics box. (The only match where we didn't have the hill).
60 with their feet were pretty effective, never got a chance to see how they worked though

Modesty aside, I like our bot (470), our downfall was miscommunication with our lead programmer about our auto code.
