I'm 6"3' and found Queens Oxford quite comfortable, long practice session before a recital and the night before.
I also agreee with the point about the small space under the lowest manual in a number of 3 and 4 manual instruments and the pedals, almost to the point where your legs can never be at 90 degrees to the pedal board, always at an angle, and very difficult to play at the lowest and highest extremes of the pedalboard.
My slight grumble isn't so much the historic organs where there isn't much space, but at historic copies where it isn't acknowleded that we are bigger than we were 300 years ag. Worst culprit? Reid Organ in Edinburgh University. Splendid sound, excellent action etc, but problems with knee space for anyone over 6 foot (and about a 34' waist), the stool doesn't move at all (up/down, or even back because the Positif is right behind you).
