Is Sanda or Taekwondo better in actual combat? We have poor public security here and want to learn self-defense!

Sanda is better. Sanda pays attention to the outbreak of strength and actual combat. Taekwondo is too fancy and impractical. Taekwondo, one-on-one or one-on-two is ok, but it doesn't matter if you play too much. However, my coach is quite strong. He just held a fight and let others fight. He just blocked himself and drove all those people away. But then again, he has practiced Sanda and has a foundation.
