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.
the feature to have the window open itself fully after a long-pull of the button feels safer to me in certain situations - means I don't have to spend a few seconds with my dominant hand off the wheel
(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)
I wait until I'm stopped to wind up or down the passenger side window, having an electric equivalent would save me.. actually 0 time. You have to stop at a toll booth to pay the toll, you have to stop at a drive thru to pay and collect your order. It's purely a convenience mechanism to save perhaps 3 seconds of time in the event it's really super hyper critical it's rolled down before stopping (for whatever arbitrary reason).
