A Holley-Edelbrock debate

Curiosity has me...
A debate between a Holley 80457-8 (600 cfm) vs. Edelbrock 1406 (600 cfm) carbs. Box stock carbs on a nearly stock small block engine. Both aluminum bodies, electric choke and somewhat economy calibration from the manufacturer.
Would there be any advantage/disadvantage using one or the other? Drivability, fuel mileage, performance etc... or just a moot point of a personal preference?
A bit may also be what the engine is lacking in terms of hot rod parts and the power it makes. I have had a 600-1860 and a Edelbrock 600 on a LD4B/318-904-3.21 set up and both performed exactly the same. Zero difference. Same mileage. No track time.
