The issue herein is that the same few faith bonuses will be chosen every game if they are not equal in strength. However, I have faith (Dohoho) that they'll either be more balanced by release or that our resident modders will make it so.
The different beliefs appear to be pretty situational, though (and this is how they've been described so far). Going by Optional's list (post #181), if you're near jungles Sacred Path will be quite powerful. But if you have a lot of stone around, Stone Circles will be. It may appear that one is more powerful than the other, but which one you go for will be entirely dependent on the situation you find yourself in. It won't be the same every time. The universal ones (Fertility Rites, God of Craftsmen, etc.) are likely to be snapped up often, but not if you're in terrain that could be better leveraged with another belief.
