I don't know what option i'd choose but the reason you get extra power from pushing on the ground is the same reason you can jump higher when you squat into the ground to "push off" for extra height.
Its like the difference of a standing in place vertical leap versus one where you are allowed one step and some squat before you jump.
So which option should i choose lol?
