Assuming there's no air resistance, they will hit the ground at the same time if dropped from the same height above the ground. (Physics is a wonderful thing).
The reason you want the mask to pop off when struck by a baseball can be explained quite simply: Any amount energy required to pop the mask off of your head is that much less energy that is absorbed by your face/skull/brain. Less energy absorbed by the face/skull/brain = less chance of concussion.
