I played Warcraft 3 at least as much as Overwatch (if not way more) and never got good at the game.
So I'd say Warcraft 3 requires more skill.
EDIT: Or maybe just a different kind of brain, I guess. WC3 is long-term strategy. OW is more short-term and even if something goes bad, your reflexes might keep you in the game.
