I voted for the AVS due to the "In General Question" being asked. As said above, this is application dependent. It is also dependent on what your comfy working on. For in general useage to a well built up power plant, there is nothing wrong with a Edelbrock carb. I don't like the AFB but love the AVS. There rock steady and reliable.
For serious engines & your looking for every last pony, I love a good Holley based carb.
If you tKe the time with the carb you have (any carb really) it will perform.
I've learned the TQ's really well. There a excellent carb if you take the time to learn them. Excellent at double duty. Though tuning parts are hard to find and the first year TQ is super hard to find tuning parts for because it is metered differently.
