Hidan may be immortal but his regenerative abilities aren't instant, meaning if a body part is actually destroyed it's gone for good. With that in mind, I think one hit from Kaguya's All-Killing Ash Bones would finish Hidan.

Hidan's jutsu also requires him to be within the symbol he draws on the ground, and I can't see Kaguya having much trouble getting him out of it. What's more, she does have rapid regenerative abilities, allowing her to survive any of the wounds he inflicts, either through his ritual or his scythe.

Kaguya wins easily.
