360 carb question - Carter c-6090

No argument from me that the TQ & QJ are 'king'.....but they can be overkill on small engines that do not require the airflow they can provide.
'Game changer' or 'runs very well' is not the same as 'best'. Best encompasses everywhere from idle to max rpm, not just the peak hp. This was shown in Nicks test where the 750 carb made the same hp as the 800, but made about 15 ft/lbs more mid range tq. The engine didn't need the extra 50 cfm & it hurt in the mid range. I know which carb I would rather use......
Another example is carbs that have annular boosters available. They usually make a little more power than their non-annular cousins. However, the boosters are physically larger & reduce airflow slightly. So less airflow, more power.
