I don't think it's as much about styles as it is about tactics.
Take away any style of fighter's ability to effectively do what they're good at, and they'll have problems. For example, if a fighter is known for having a great jab, and his opponent is able to catch that jab, or better yet catch, and follow with a straight counter over the top he'll nullify that fighter's ability. He'll cause the fighter to question himself, break them mentally. Identify what makes them good, and keep them from doing it. Your base style may not be the deciding factor but your tactics may be. Military theorists have referred to it as the opponent's Center of Gravity. Identify what that is, and take it away from them.
