This. On my hybrid, I find myself moving my hands a lot from a comfortable riding position to a position where I can shift. On my road bike, my hand spend 95% of their time in a position where my palms face each other. This is more natural and less stressful. I can ride and shift with my hands on the hoods. On drop bars, you will be more bent over instead of upright. It will take some time (a couple of months if you ride 3-4 times a week) before you body adjusts to this riding position. While the majority of commuter bikes I see at work are flat bar bikes, I personally favor road bike riding position. Once the rainy season is over, the hybrid will be banished to the depths of the garage until next winter. Or if I want to leave it locked to a rack while running errands.

I you plan on doing frequent 40 miles rides, the road bike will be faster because of the more aero riding position. It will be more comfortable because of the better hand positions.
