I like Philosophical, however I play CE more than I play SE. Thus, the Philosophical trait is better with other players. Even so, those extra GPs along with the cheap universities (which are extremely expensive without this bonus) is not something to ignore. I rate Philosophical 7/10.
I like Aggressive. The free Combat 1 for melee and gunpowder units is a simple but major advantage to warfare. Along with the cheap barracks and dry docks. However, the Aggressive trait is only suited for a warfare game, thus I rate it 6/10.
I love Spiritual, it allows easy transition to many strategy in a matter of turns. Building military with military advantageous civics and then altering to economy civics is a major tactic in Civilization. The cheap temples, however, I barely take advantage of. I hardly play Religious Economies. I rate Spiritual 7/10.
I love Organized, however, in some cases, it does not help me because I do not have a big empire. Organized is only useful when you got tons of cities, so that not only would the civics maintenance decrease, but the cheap courthouses is a major boost. I rate Organized 8/10.
I like Expansive not only because of the cheap workers (which is nerfed by the fact they have to be built by hammers in order for the benefit to work), or +2
but mainly because of the cheap buildings. A cheap granary, nothing something to ignore. I rate Expansive 7/10.
I somewhat like Industrious because it allows easy wonders and forges. However, I don't often build forges in my game because they are expensive (even if they are cheaper with Industrious) considering how early they come. Also, wonders I usually do not prioritize (except for the usual ones like the Great Library and the Taj Mahal). I rate Industrious 5/10.
I love Charismatic because if you build the Stonehenge, you immediately get +2
in every city, along with the border pops. Along with that, its great for warring because you need 25% less experience for the a promotion. In other words, its suitable for any type of game. So I rate Charismatic 10/10.
I somewhat like Creative. It allows quick border pops and culture pressure. Along with cheap libraries and theaters. However, since I don't approach libraries and theaters much, and its a waste of a trait when you can just build a Momument to open your borders. I rate Creative 5/10.
I somewhat dislike Imperialistic. Quicker settlers, however, they have to be hammers for this effect to work. In my case, I often don't use hammers to build my settlers because my capital, which is usually my settler spammer, usually has lots of food and I use that instead. As for the +100% general bonus, I'm fine with just 2 GGs in my game. One for a Medic and another for an instructor. So, I give Imperialistic 4/10.
I quite dislike Protective, basically the only trait I really hate. The only benefit of it is the cheap walls whip for money. However, since this is an exploit, I never use it. The free D1 and CG1 for archery and gunpowder units is lame, after all, in warfare I am practically always on the offense. I rate Protective 2/10.
I love Financial, especially since I am a CE player. Riverside cottages with Financial is crazy. So even though Financial doesn't give as much as other traits, its only benefit is great. I rate Financial 8/10.
The king: Charismatic!
saved per cathedral increases with map size as you need more temples/cathedral on a bigger map (5 for huge?)
points 
to die down before whipping again
