that scan of Dr. Strange just being an arrogant and condescending chap to Thor got me wondering. he has a kick ass library, is highly erudite, obviously refined and classically educated... basically he has all the cliche traits of an intellectual of the highest order. the literary type, not the nerd in a lab coat (Reed).
Doom's something of a different animal, he's driven and brilliant. he has a scientific bent, but clearly doesn't seem to gain much pleasure from scientific discovery, unlike Reed. it is merely a means. also highly adaptible - learning magics which are fundamentally founded in the irrational as opposed to science.
Banner is just a Reed-mold genius, here purely for guaging Dr. Strange.
Stark is your regular highly educated and intelligent chap. uber smart, but not soaring in the stratosphere that Reed/Doom/Banner et al inhabit.
also, I still haven't really found a 'placing' or ranking for magic. Galactus > Cyttorak seems to be undisputed. yet Juggernaut > physical force still holds true to many here... which is a bit of a conundrum, to me. to say the least.
