Jeet Kune Do> Tae Kwon Do because by the time Tae Kwon Do has matched the attacks, Jeet's speed has completely smashed them
Jeet Kune Do> Capoeria because essentially, Capoeria's force isn't that strong. Jeet's endurance would wear Capoeria out and then crush them
Come on...Do you study martial arts? Because if you do you SHOULD know that it depends on the artist themself, as the posters above said. BUT if it were by style this would be my analysis:
To your first analysis of JKD and TKD:
TKD is also known for it's speed. Yes mostly for kicks but speed+strength+kick = pain. I have never really seen JKD in action before so I really wouldn't know much about it.
To your second analysis of JKD and Capoeria:
Do you know how many kicks/attacks someone that studies Capoeria can get out? Easily they can throw like 8 attacks. Even if the JKD practitioner were a hard-ass, literally, one open spot and a Capoeria practitioner would have 6-8 shots in.
Again I don't know all too much about JKD but what you said sort of offended me that you would say what JKD could do but not what the other forms could do.
