If they are all in their CE variants then Team 7 clearly wins.
Sasuke>Gaara. He breached his ultimate defense easily and has the speed to outspeed his sand let alone simply evade it. A 2nd Chidori would've spelt the end for him. Sasuke can also squeeze out a 3rd Chidori if needed but after that he's out of the game just in case Temari and Kankuro are more difficult than expected. I doubt he'll need a 3rd Chidori to take them out anyway.
Naruto w/ 2k Barrage was beating the hell out of Partially transformed Gaara and forced him to level up to full Bijuu Mode, so him w/ Sakura's support should be more than enough to defeat CE Temari and CE Kankuro.
Sasuke>Gaara
Sasuke>>Temari or Kankuro

Also remember him beating her pretty easily without his Sharingan but I can't remember if it was the anime or the Manga.
