I think that traits are only judgable combined. That being said, I recently tried a game of Cyrus (Cha/Imp) of Byzantium. When I found two beautiful chokepoints close to Justinian I of America. I think that without Imperialistic, I wouldn't have been able to get either, and the northern one (Adrianople) managed to get pretty good production, as well as my best gold city and damn close in science (CE with two spices, also had confucian wonder). However, charismatic really did better than aggressive could've done in my game, because I got many powerful cataphracts and cavalry after I got the tech lead, and also got some pretty powerful warlord units (uber-rifle w/60+ EXP and super medic unit, among others).
However, if I was in a different situation, such as being boxed in early by more powerful neighbors, it would've probably financial and industrious that could've helped me the most (and that did happen in the aforementioned game to an AI who had two cities until I had gunpowder), given financial to play catch up and industrious to build cheap forges and build armies that way.
