first off the cloak was a temporary power up from naruto which means le cant get that power unless naruto gives it to him...
also madara not obito, but anyway madara wasnt trying to defend himself either, he stood there with his hands folded, he could have easily suck that chakra cloak off of lee with preta path or put up susano, madara didnt fear that basic kick nor any other cloaked shinobi... also any form of lee cant touch obito
also thats your opinion that lee with cloak is the strongest out of k10 which isnt true because he couldnt touch neji and choji with cloak shits on lee...
