For me a long time ago it boiled down to this perhaps overly-simplistic point:

One view exalts God as all-knowing and all-sovereign. The other paints Him as a frustrated diety who must pace heaven's floors, wringing His hands, hoping that someone on Earth will let Him have His way.

Any doctrine which fails to acknowledge God as God just cannot be true.

Simplistic? Okay. I'm a simple boy anyway, and I'm in good company according to 1st Corinthians 1:26-31.
