In my experience with the Q-Jet question in the Toronado world, those who dislike the Q-Jet are usually those who don't have the patience or knowledge to rebuild it properly or dial it in correctly. They always choose the Edelbrock and suffer semi-reliable but mediocre performance.
There are dozens or maybe hundreds of variants of the Q-Jet but many people think they're all the same.
My Toronado had the wrong metering rods in it when I got it. Once it was rebuilt correctly to 1966 Toronado specs, that car could kick muscle cars and hot rods to the curb.
I think the Quadrajet is probably the best 4 bbl carburetor ever designed.
