Heh, sorry to say, the fact that you say "I never go for cultural wins" and then go on to tell me that the benefit to temple production isn't good kind of invalidates your position. I could tell you that Charismatic kind of sucks, but I am a peaceful builder exclusively, and I'm sure you'd jump on it
You get cathedrals with music and temples way before that - if you're sitting there telling me that the bonus isn't helping you when you get to the industrial era, it's pretty obvious that you're just ignoring the very great boon to a type of victory that this bonus is helpful for. If you want a cultural victory, getting things early pays off - not "Well, I'll just build my temples when I have forges, factories, coal plants, levees, etc etc etc - then the bonus from spiritual is useless!"
And I wasn't meaning that philosophical is helpful in going for cultural wins by people "turtling down and becoming someone's vassal with the plan to win 1000 years later." I was meaning that it's can make for a very powerful, flexible specialist economy that is in many was much more resilient to enemy incursion and much faster to reach full speed than a cottage economy. Philosophical is very powerful on deity because A) you don't need any particular terrain type to make it work outside of having food production, B) you can switch scientists to engineers in a pinch if you need production, and vice-versa, while cottages are pure money until you hit US, and B) you can't pillage specialists and camped super specialists, unlike cottages. For this type of economy, philosophical is *incredible*, and frankly, it's simply not a weak trait - just doesn't suit your playstyle.
As for your "boring" comment... Believe it or not, I find the cookie-cutter rush tactics most warmongers use to be boring as hell. Cultural and diplomatic take *so* much more planning and finesse, I tend to find them much more interesting victory options.. And I usually go space race ahead of late game military victory just because any game I win via space race is one that I'll have played a full game, not won by the time I've got riflemen.
