>>281263138The whole point of the Gaara fight is that were they fighting a fair one-on-one fight, Gaara would've most likely won convincingly, but upon realizing this, Deidara decided to fight dirty and took advantage of the fact that they were fighting directly above the Sand village, and so he dropped a nuke on top of it to force Gaara to focus all of his power and attention on protecting it, and used the opening to deal a near-fatal blow. Deidara had no such cards to play against Sasuke, and he still nearly won.
