Holley's science vs Edelbrock simplicity?

I've been running an early1970s 750DP since about year 2000. After the initial tune, I've just been driving and driving and driving, to the tune of over 100,000 miles. Carb is sorta worn out by now........ but it's like the Energizer Bunny.
On other combos , I have had TQs and AVSs and AFBs, and after the tune went in, I got no favorites. Well except for the TQ moan.......... I love that,lol.
Run whatcha got.
If yur buying used, take what comes .
If yur buying new; flip a coin.
If you got the coin, maybe get a Goggle Valve and write a review on it. I'm kindof eyeing that thing.
