Oh cmon, 16mph difference in top speed is still "much the same". Yves Rossy's wing: Optimized for forward flight, has VTOL capability, bulky. Zapata's flyboard: Good middle ground, VTOL with decent speed, restricts ground movement. Gravity jetsuit: Optimized for hovering, lightweight, can walk in it. They're all doing much the same thing though, strap some jets onto a human and allow them to fly with VTOL.
