Holley's science vs Edelbrock simplicity?

Totally disagree with the title. I've owned both. Still own both. I do not see any more simplicity with a eddy vs a Holley. Try changing a needle and seat and adjust a float level on a eddy as fast as the 1 minute that I did in this video on a Holley.

What about tuning on a 4160 style holley are they as simple and as easy as the double pumpers?
