Stay out of boost during daily driving and your gas mileage will not change.

yeah as long as you can stay out of boost form either one of the blowers you wont see much change in gas mileage

Not necessarily. All modern positive displacement blowers (Roots style or Screw type) utilize a built in bypass valve system, so you're not going to see positive manifold pressure (boost) without getting your foot into it with the Kenne Bell either. No additional boost, means no additional fuel (other than what’s already prescribed by the ECU under vacuum) keeping gas mileage the same as it would be stock. A positive displacement blower can easily be brought right up to redline without seeing any boost on the gauge.

Real answer....6-in one, half a dozen in the other. Both are going to see similar mileage numbers.
