You do have a point that any drop in the handlebar basically just takes away from the usable adjustment range unless I got so low that I wanted the bars lower than the headset (not likely). I do think the ones with some drop look a lot better though. So if the drop didn't force me into getting a taller stem, I'd take a drop bullhorn with the stem out an extra inch or 2 over a flat bullhorn with the stem a little lower if everything else was the same.
