When to normal map.

I know this must sound very stupid. But is there a rule, some nugget passed down by sages that tells the apprentice when to genuinely normal map, or when to just use Crazybump/NVidia Filter?
Inversely what things should be left to geometry as opposed to represented by texturing?
forgive my ignorance in advance, I have had no one explain such things.
The hows, and the whys are not always synonymous.
