The torque loss that people are talking about does not happen when at a consistent speed. When you switch gears your clutch pulls your flywheel down to a slower speed. When this happens, then energy stored in the engine/flywheel goes to the wheels. If you have a lighter flywheel, less total energy is transferred during this process. However, all the energy originally comes from the engine. You can either accellerate slower and give your car a little boost during shifting or you can accellerate quicker. Personally I'd rather keep my power rather than loan it to the flywheel and only get it back when I launch or switch gears.
