The one thing for sure is that weight is easy and accurate to measure and I know with my pulleys I saved 5lbs off the front of the car.

I have seen the stock vs Perrin lw, vs fluidampr dyno comparison. Lw crank seemed the worst. Stock was more balanced. And fluidampr had a much better top end for a slight decrease bottom end (although maybe something else was at play for it losing in the bottom like 1 IAM got pulled from previous runs)
However I have seen some s2000, mustang, and VW (not sure model) which all showed at least a solid 3+ hp/torque across the entire power band. With hundreds of people in those forums praising the pulley. It must not be as well known / tested in this community for some reason. Maybe ppl are to stuck on the LW pulley to try it.
