They stack up better, IMO. I have run a piss load of them. I think they're the best carburetor ever made. That's how it is. You either love them or hate them. PLENTY of stock eliminator records have been set and broken over the years with the TQ. IF they have a shortcoming, it is their primary metering system. In engines with a low vacuum signal (big cam) the metering rods get confused at idle because the vacuum signal goes away. So, they tend to bounce at idle and they do not idle very crisp.....but they still work fine everywhere else.
There's a seller on Ebay called ninja fuel systems that sells tuning kits for TQs that include different springs. That might be a cure. I have also seen people REMOVE the metering rod piston spring altogether, though I have never tried it. For a dual purpose mild to moderate build, they simply cannot be beat. They do have a learning curve regarding tuning, but once you see what everything does, they are easy to understand. They are one of few carburetors that can run just as well on a slant six as a 440 with only minor tuning mods. Also since their primaries are so small, they can get unbelievable gas mileage on the street with mild gearing.
