For example, the Eurocopter X3 configuration is more compact, able to land and launch in tighter spaces even than the equivalent tail rotor helo.
It's also no taller than a normal helo, which is a problem for counter-rotating props.
It has fewer moving parts so it's almost the same maintenance as a normal helo.
The winglets are never blocked by tilt-rotors, so they can mount missiles, rockets, and guns.
But still, it's not stealthy either.
