In Shippuden I'd have to say Sasuke's stronger. There has been no proof episode-wise on who's stronger but in the games Sasuke is a lot stronger and faster than Gaara. Gaara is often weighed down by his gourd. Their strength is closely matched but Sasuke IS one of the two main characters in the show. He's got electric jutsu, Sharingan, fire jutsu, speed, a sweet blade, and other tactics. It'd be a long and tough match but I think Sasuke would end up winning. Another way to support this answer is that Deidara is the one who beat and captured Deidara. If Sasuke beat Deidara then it adds up to say Sasuke is stronger than Gaara also. It's just a matter of opinion.
Sasuke
sasuke is way stronger than kankuro
Yes he does,in the Forrest of death while Gaara was trying to attack Sasuke Sakura jumped in frount of Gaara to pertect Sasuke but Gaara pined her to a tree with his sand to keep her out of his way.

naruto will be stronger in naruto shipppuden he will save konoha it might be sasuke becasue he now got a new sharingan and naruto lost his kuubyi power I don't know what going to happen when he meets sasuke again
Itichi is stronger because is he can almost beat killer bees biju then he can kill garra. also his jinkirikki is absorbed by the akautski. so itichi would kill garra
Sasuke
Sasuke is more stronger than Shikamura but he is smarter
Naruto is indeed stronger than sasuke
sasuke is way stronger than kankuro
Naruto is stronger then Sasuke because in episode 240 until 254 he will obtain kyubi mode that is stronger than Sasuke's susano
Kakashi clearly because Kakashi Is His master and he taught him The Chidori and The Sharingan and Orochimaru tought Sasuke some things but Kakashi is stronger than Orochimaru before he died that's why Kakashi IS stronger than Sasuke
Rock Lee is stronger than Sasuke for a limited amount of time in the chuunin exams. After that, Sasuke is always much stronger.
Sasuke
Yes. Even though Garra no longer has 2 tails he can still use sand (this is proved when he has a little battle between him and sasuke at kage summit)
Yes he will.
