What is the best?

I told you i was loaded with questions, and this is one of em. What is the toad-style of martial arts? By that i mean, which martial arts is invincible when it comes to defence, is there a martial art that focuses more on defencing and countering then dealing the first strike? If there are, which one is the best?



Now i know there is no such thing as the best or perfect martial art, and that its the individual practicing, but lately i had a conversation with a wing chun practitioner and he was ''bragging'' about how he would block all my punches, as they learn that. I as a boxer also learn how to block and dodge them, but we learn it in combination with striking. So is there anything like this, a martial art pure focusing on defence? Thank u in advance.
