It has been awhile since I've played but with normally playing huge/large marathon/epic immortal/diety game's I would say top tier is Ind/Phi, small gap then financial, noticable gap then Spi/Cha/Imp/Cre imho. The fail gold for keeping the slider up is what in my eyes makes Ind the best in addition to the speed up for certain key wonder's you want to build the best. Closely in second I'd say would be Philosophical only because it starts to drop off midgame because after 5-6 GP the amount of GPP needed for additional GP rises substantially so there are some diminished return's on it in comparison to Industrious. My group of the next 4 traits wasn't in order but they all have the same effect and bang for your buck. If I had to rate them I'd say Cha, followed by Cre, Spi, then Imp. You don't have to war often but it is more efficient to take cities at the difficulties I play at so that's why I'd rate Imp last. Spiritual is dependent on if you want to micromanage and if you like to win culturally/religion/tech route more so over Dom/Conquer style. I value creative I would say reasonably high compared to most but it is powerful for land choking peaceful civ's plus the cheap libraries are great. Charismatic I feel is fourth because in a stack of doom you really do need I'd say 8-15 well promoted killers and needing less experience for promotions is very great to get the core of your SoD up and running.
