I've had cars with electric and manual windows. I'm 27 (so you don't think I have been biased by a lifetime of manual) and I prefer manual crank in all but a single use case: the situation where I want to wind up or down the passenger side window.
(and also more convenient in other situations where I need to quickly open the window and actively drive at the same time, e.g. toll booths, drive thru's)
