Of course the owner of the DYNO could make adjustments to his DYNOPACK to account for the higher HP. Not sure I don't own one just stating what I know from Experience and what logic tells me (power is lost at wheels)

So you have dyno'd your own personal vehicle on both types? and with almost all things being equal, have seen the drastic differences?
-Church's automotive,
balloon dyno is legendary... and shouldn't be included in this convo.
All load based dyno's can be altered to show fictitious gains, by adding correction factors etc.. which is why most consider the Dynojet to be the defacto standard.
Regardless, dyno #'s should only be used to show increases from baseline. Trap speeds will tell you what you are really putting down.
