Pretty sure Sasuke gets pummeled by both of them.
Ichigo packs a lot more firepower than Sasuke at his best and his speed feats are much more impressive. More likely than not Sasuke would be too slow to properly manage a genjutsu on him, and really the only chance he's got is to use Susano'o right off the bat. If he doesn't, there's really no way for him to stand a chance. Especially considering Shikai Ichigo alone has a Getsuga Tensho this strong:

Of course, it also depends on what form of Ichigo we're referring to. If it was Post Dangai Ichigo then he'd win pretty effortlessly with Mugetsu, even without it he shouldn't have much trouble.
Luffy's also leagues above Sasuke. I can't recall any Sasuke speed feats that dwarf this:

Not to mention that he also has Haki along with his insane speed so he should easily be able to predict Sasuke's attacks.
Also, no way Sasuke's gonna tank hits from a guy who could do this:

Too lazy to find other scans but if you look at the size of Noah and the fact that it would pretty much demolish Fishman Island by falling on it, it's pretty clear how strong Luffy is to pummel that to nothingness. Sasuke has no way of standing a chance here.
