It's an interesting debate for a number of reasons. It involves some of the most fundamental issues in metaphysics and theology. The debate is timely, because it is often said that the new atheist movement falsely supposes that God is a being among beings. It is striking to see someone on the theistic side of the fence defend a flat sort of ontology against the radical ontological distinctions that have been traditionally drawn.
I won't summarize the debate. Interested readers should just read through it chronologically. But perhaps a few comments on Tuggy's most recent response are in order.
