Gestures are going to be the most comprehensive, as it allows "real" interaction with the objects overlayed on the scene.
Try pretending to use a virtual keyboard or touch interface floating in front of you for even 2 minutes. Without support or a a task to grasp onto, the large muscles in your arm quickly become fatigued. This is called the "gorilla arm" phenomenon. It looks great in movies and sounds great in SF books, but the reality is different.
That's what's typically used in VR.
In VR, much of the fine interaction is handled by thumbsticks and buttons on the controllers, with only an occasional large physical motion, and people still find it fatiguing. Now imagine if all the thumb/finger swipes you do daily on your phone replaced with pawing at the air in front of you without the benefit of physical controls to supplement. You'd quickly grow frustrated with such an interface.
