Star Wars Battle Royale - Who's Superior in Fight Style?

If all the droids from Star Wars are duking it out, who's superior in fight style? Or two. I'm gonna go K2SO. He's got the height and the reach on all of them. Our two can fly. The K2SO projected arm up and slammed him to the guys. You start what happened to the last droid that tried to grab our two. He got set on fire turned to bacon. And when he sprays that sauce on you and sets it on fire, metal turns to bacon. We'd really like to see an R2 versus chopper fight. That is where my big money is coming in. It would be great.
