Best 1 barrel?

In your guys opinion what is the best 1 barrel carb for a 225 /6? Im looking for reliability mostly. Power or economy. Or would it be best to save and switch to a 2barrel? Which 1? Also ive heard that parts stores carbs are no good? What kind of issues have you ran into with them? Where would you suggest picking 1 up at? Thanks in advance for the help.
