I don't see a battle between them that doesn't wind down to one of them outlasting the other, up to and including their actual canon fight, in which Itachi dropped dead while Sasuke was still standing. They've been shown able to counter or dodge each other's everything.

If with Sasuke we mean the idiotic Sasuke that fought B or the five Kage charging into the fights metaphorically blind, spamming everything he had left and right, then Itachi wins merely by outsmarting him.

If we mean the Sasuke who fought Deidara, Itachi in canon, or Naruto at the end then that Sasuke would just carefully force Itachi to spend everything, taking advantage of his larger chakra pool... just like he actually did.
