I feel like I'm asking "would you choose a red car or a blue car", and getting the answer: I like yellow motorcycles.
You are asking the question of whether one likes worms with strawberry sauce or chocolate sauce and the answer is "I don't like to eat worms" and you keep insisting "yeah, but which would you prefer?" It's a question that cannot really be answered because it is orthogonal to how most people in MA think about a potential opponent, whether on the street or in the ring.
There are some arts that lend themselves to certain kinds of fighting or certain kinds of sport, but even within a given art there is as many ways of training as there are reasons for the people to be in the art. Not all arts are created equal, but no art is to be trifled with on the face of it.
I'm going to fear a person far more if he's a nasty SOB with an attitude and a chip on his shoulder far more than I will just because I knew he practices BJJ or Taekwondo or Muy Thai or Karate or anything like that. As a matter of fact, I would *love* to know that he practices just BJJ or just Taekwondo because then I know what he's thinking better and I better know how to counter it.
