Help me pick a new carb

I have never seen an edelbrock that didn't have a huge vaccum leak at the throttle shaft, I have bought two edelbrocks brand new, one performer and one avs and within 3 months there was a huge vaccum leak at the throttle shafts.
I got tired of trying to tune the edelbrock's with vaccum leaks and bought a quick fuel super street series 680cfm vaccum secondary carburetor and couldn't be happier with it.
It comes with Teflon slabbed throttle shafts and Teflon throttle shaft bushings. A 4 corner idle changeable idle air bleeds and high speed bleeds, changeable idle feed and power valve channel restrictors. I just barely got my quick fuel dialed in and I must say it runs great and it has way better throttle response compared to the edelbrock. And it is only 150 bucks more then a brand new edelbrock avs and it has way more adjustability on it.
