I broke the tie!

Actually, I like them both.

I nailed a LMB yesterday on a shakey head presentation but I have caught my largest bass on a drop shot.

The drop shot did not work yesterday for some unknown reason but they hit the shakey head.

Go figure.  

They both have their time and place.

A drop shot was designed to present a bait off the bottom as when they are suspended off the bottom.

A drop shot allows you to tie that hook 3 ft off bottom if needed.

As Tin noted, they each have their own place and time.  

Both presentatios have vertical and horizontal capabilities.
