Who currently has the best defense in NV?

[Chatte]

Gaara's sand I think.
Even Naruto said that that's the best defence he encountered.

gaaras defence sucks now adays alot of characters can bust through that shit

 

[ghost nappa]

Tobi's intangibility. And why is Sasuke's susanoo up there instead of Itachi's which has yata, and Madara's which can become enormous?
Of the three given choices, I'm going with gaara
