Great topic! Looks are nice, but intelligence is just so much better if I had to choose. Talk geeky to me anyday. I can't promise I will be able to keep up, but I am happy to listen and try. An intelligent mind, someone you can have a conversation with and learn something new from is just wonderful! I also have a penchant for what I like to refer to as "engineer brain". People with engineer brain process things so differently than I do that it fascinates me. The ability to create and problem solve is just hot, hot, hot!
Anyway .. Not sure you meant to inquire from the ladies.
Sorry for the interruption..
If you're planning to spend only one hour of your entire life with this choice I could see how there may be a complete toss up considering how men by nature are very visually driven. However, if you are considering the quality of hours, days, weeks... the answer would probably not be the same.
