Taekwondo is better, and the probability of serious foul in judo is very high (just watch a game). And the hand movements are more indulgent. Taekwondo has strict rules, but it is easy to get hurt in actual combat. Kung fu is mainly about legs, and it is advocated to kill the opponent with one blow.

Judo is easy to be stabbed (too close to your opponent) against gangsters, so Taekwondo is better. Taekwondo is sure to win judo, which is flexible and powerful.
