The people in RWBY are superhumans, though it is hard to give an objective estimation of their strength and durability because the show was incredibly inconsistent. They are supposed to have a natural magic shield called Aura, which allows them to survive crashing into concrete walls at 50 MPH and other similar fatalities, but then in other scenes people get decapitated like they never had Aura protecting them at all.
People in AoT are fragile humans and the only thing they've got going for them is the 3D maneuvering gear. The Huntsmen will easily win with their superhuman strength and durability, not to mention their individual powers, and then their Dust-powered equipment. Huntsmen in RWBY casually dispatch humongous superpowered monsters so the Titan Shifters will go down too.
