I like leaning forward pretty heavily, but I reduce that slightly on some of my commuter bikes. Being slightly more upright gives my neck and shoulders some agility to look around. But my "slightly more upright" position is still very bent over for many people.
Generally, I use drop bars for fun or long rides and upright bars for short or city rides. But I've recently started commuting on a Bianchi Volpe which is nominally a cyclo cross bike. It has drop bars, and I feel extremely comfortable on it in traffic. I can't explain why that is. I should take measurements, because the fit seems accidentally better than on any bike I've had.
