Well, I'm not sure I would describe myself as "passionate" about it, but I tend to ride in the drops a lot...easily 50% of the time on my modern STI-equipped bikes, and probably 75% of the time on my old (1985) Diacomp-equipped bike.

Not only are my hands more comfortable in the drops, but my whole body is more comfortable, and I feel more in control of the bike when there.

Probably worth noting that there's more than one "in the drops" position on a drop bar. I can think of nine different positions that I make regular use out of, four of which are "in the drops".
