I like using the drops for fast bursts on the flat, going aero downhill, headwinds, and sometimes just for a change of position - I have long term chronic back pain (cycling didn't cause it) and staying in one position for too long makes it worse, so swapping back and forth from the drops to the hoods or ramps quite often helps. I don't like to slam the stem right down either, but do want some drop to the top of the bars.
