Why is it better than Classic and other mythologies?
It's not. It's actually PRETTY useless.
It's possible that it's metaphorical for SOME stuff, but as far as the symbolic worth of it- it's not very applicable to human life.

I would agree with this. Religion is used to provide a framework for life. Deities represent various archetypes, the festivals mark the progression of the wheel of the year.
Lovecraft's pantheon is a set of horror characters. He surely never intended anyone to actually worship them. They're not even really scarier than the scary deities of the old world. Go re-watch the "Night on Bald Mountain" segment from Disney's Fantasia. That's good stuff right there.
