Karate or Taekwondo - Which martial art would you implement to your MMA skillset?

[Intermission]

TaeKwondo has more hip into the kicks but they dont have sweeps (I guess kyokushin doesnt either these days) so they get complacent about throwing it with less rigor...

Thats the only big differences I can tell.

Kung Fu challenge below! TKD guy goes down several times, fights as if its sports taekwondo.
