Holley's science vs Edelbrock simplicity?

I like the idea behind the AVS2. How is it working for you?

Still messing with the jetting/timing but the throttle response and low speed qualities seem to be an improvement. The 750 Holley (Qickfuel) I was running made much more full throttle power. But that could be due to tuning or the fact that I chose a 650 cfm AVS.
