What you get is both downsides rather than both advantages. It can’t fly fast enough for fixed wing, nor can it fly slow enough for rotary, meaning it can’t effectively be escorted. It doesn’t have the range or speed of fixed wing, nor can’t it hover as well as a helicopter. It requires special logistical channels. It’s finicky to fly and high maintenance. Because the rotors are so heavily loaded it creates significant rotor wash and it’s especially susceptible to vortex ring state. It can’t glide like fixed wing and can’t autorotate like rotary for a power loss in flight.
It’s garbage. The idea of using these for rescue or VIP transport is laughable.
