"Carries more, flies faster and farther" is just salesmen speech. Carrying capacity is 24 men or 20,000 lbs. (Or 15,000 lbs externally.) Range for a full amphibious assault is 184 km according to Boeing that builds the thing. Sure, it's got a lot of range when empty, but that won't help the Marines that want to reach the combat zone. A Special Ops squad will get better range, of course.

Unfortunately for the poor Marines that will be riding in it the Osprey has troubles. The propulsion system is complex and vulnerable to damage, thanks to the tilt-rotor system that's supposed to make it stand out. If one engine stops there's a cross-coupling that will transfer power from the other side so both props keep running. That's a whole lot of vulnerable parts right there! If it fails the thing comes down like a brick. And this craft is going to be the first one to arrive in a hostile zone, taking fire from everyone and their inlaws.
