You'll get more usable power from the Gene chip. It's more efficient.
To put it into perspective. If you know anything about car stereo amplifiers, they are rated by class on efficiency. A class C amplifier is 50% efficient, which means 50% of its power is measured in heat dissipation. So if you have a 1000w Class C amp you're actually only getting 500w of usable power.
Works more or less the same way. The Gene chip I believe is 93% efficient (might be one or two, up or down). That's why you will hear some reviewers say the Drag mods feel like they hit harder than other comparable non-DNA or non-YihiSX chipsets.
