For me, when climbing I like the hoods or bull-horns. It leaves my arms in an "untwisted" position, and a firm grip on the bars. The drops are for aero, long-sprinting, and decents.... none of which last all that long. At one point, I did ride them exclusively, but not any more.... it's mainly hoods.
That's why I put bull-horns on my FG... I wanted the "hood" position while only running 1 brake.... and without fake hoods, or unused levers.
