I often talk to hunters and former hunters. Many of them miss the drives because they were social and not as boring as a long sit in the stand.
It depends on type of cover, how dense, exit routes and the setup. One thing often overlooked is wind/breeze direction. Ideally I want the 'pushers' to let their scent do most of the work. I also want standers in a position where the deer don't smell them as they go. If they do they very well may slip to the side.
This all means one shouldn't do the same drive every time, conditions and wind changes. Just drift some scent into thicker cover, deer will get up and exit at a speed that allows a good shot. At least a better chance than the hooping and hollering of yesteryear.
To answer the OP's question, noise and speed seem to confuse the deer the most. When I did stick around for the may lay, we found that the Blitzkrieg approach got them moving forward better than the quiet approach. They were more likely to sneak back around us if we tried to just do a slow push through the woods.
