Perhaps we can simplify the question into "Are you competent?"

Cos ultimately competence is more important than stylistic differences. Now that's not to say that it's wrong to ask about styles or to discuss them... but simply not consider styles as the penultimate factor that defines fighters.

Another factor to consider is finding a good teacher. I've seen lots of students who study traditional martial arts styles, but are not competent fighters because of the teacher. For example, I've come across a lot of schools that are really good at teaching forms, moves etc., but hopeless at teaching application. So their students become really good at performing the movements and are probably brilliant at passing grading exams... but are incompetent fighters.
