The most efficient way of putting up drywall in my opinion is with a screw gun. They take half the time that you would have to drive a nail in. Then there is liquid nails (that I don't like)If you don't have any stud to drive into.I would say its up to the person's own preferences. I bought a screw gun and always have a job for it,it's so useful especialy for my wife. Good Luck on you project,and wait on somemore replies.
