Assuming that you have oil, what would the benifit be running one over the other?

I have heard that the hybrids are more efficeint than B codes, but that B codes have a better ratio (7:1 vs 5:1).

Any thoughts?

the main limitation on HEUI injectors seems to be the Poppet valve, so the less oil you have to flow for a set amount of fuel, the faster you can get that fuel into the cylinder, the lower the pressure losses across the Poppet, and the more power you make.
Summary? Hybrids seem to win in the real world. Now, don't get me wrong though, B codes lay down some serious power as well, but My vote goes to the hybrids
