Smartest - youd get rich from it anyway, and being hot comes in different ways
Edit: On second thought I quite learning stuff and being wowed and knowing the most in the whole world might actually be quite boring? So Id go with richest; nice easy life. Everybodys' looks wear off as they age so itd be for a limited time and youd be wanted for all the wrong reasons (goes with money too I guess but you could hide the fact..)
