Bridge builder. you stated your question in a way that is hard to answer. the road glide and road king are two very different animals. you ask if there are any differences other than the obvious. well duh, the obvious differences are the differences. engines and and drive train are identical. a road king properly set up will not buffet the rider. neither will it have the wind protection of a frame mounted fairing. I believe the general consensus is a road glide is the most stable HD in crosswinds. but they are all pretty good in that regard.
