Erm, considering that an MP-05 SP LE (higher pressure drop than the G4), MP-1 GPU (highest pressure drop amongst commonly available GPU blocks), and BIP can't even take a DDC-2 w/top below 1GPM... I'd think that hardly anyone would run into a situation where the stock DDC-2 would win out (as far as flowrate is concerned).

Maybe if you were on 1/4" ID tubing and had a jillion blocks in your loop that were similar to the NexXxos XP in design...
