all of them, except UFC cause it is a company. anyone of those can overcome any one of those with the right training, teacher, practice and dedication,
if your looking for specifics, savate probably teaches most powerful kicking, boxing punching- although Bas Rutten is a kickboxer and had the most powerful punch on FIghtScience, grappling probably catch wrestling or sambo. but it is all in the teaching and practitioner's abilities as well.
just remember there is no "best all around package" that is why they needed to mix martial arts in the first place
and also, some claim BJJ to be the best, consider this a catch wrestler named kazushi Sakaraba beat 4 Gracie's some out of his weight class...
