Unless you buy very expensive special pots like these https://www.mouser.com/ProductDetai...iMZZMukHu%2bjC5l7YX%2b949kp6rphnsVqb2h/%2bfA= It really doesn't make a difference. Most all of the pots are imported from china with wide tolerances. Even the size really doesn't make much difference in quality, There is a perception that dime size pots are inferior. Most of that is due to the fact that they are much easier to ruin when soldering too long. So people ruin them a lot.
