Vader got hit by emotions too around the same time. He wanted to be a dad and didn't seem as into a fight to the death with his family as Luke was.I doubt Rey's street-wise skills (part-timing with scavenging) are nearly as effective as Kylo's dedicated training from the order. Also, Rey got bopped into a tree and hit the ground at the height that could fracture bones.
IIRC Luke got mad strong after getting destabilized by Vader.
