Any of those motors will be fine and all about the same eff wise. Its just depends on how much spd you want out of it. Even the 3D will be plenty fast unless you are building a 60mph street rocket.
Here's the guy from Tekno running a 3D on 6S iin an 8T in truggy class and destroying everybody. BL motors don't need massive rpms to be fast. I'd make my decision on desired speeds rather than minor eff differences.
