A fair point. Ben turned into (but didn't originally start as) a Palooka. He tended to put women on pedestals, as they seemed generally unobtainable to him. Professor X was, at least until the 70s, pretty much a sexless being when you think about it. He was the stern father figure and crippled besides.
Reed is SMARTER THAN YOU (and worse, knows it), a war veteran, has super powers, is rich and NOT ONLY does he have a girlfriend who looks and dresses like Jackie Kennedy, he's aloof enough to act like it's No Big Deal. So it's easier to see Reed as a dick, since he really doesn't have any of the disadvantages of most of the other super-dudes of his time.
I just often think it's funny how folks selectively judge characters from the mores of one or two previous generations. Reed IS pretty patronizing to Sue in the early stories...but those stories are now literally 45 years old. Consider the fact also that Sue didn't decided to stop being a 'girl' until 1987.
