It doesn’t matter when you are using a ratchet. The ratchet gear has many detents so it can be positioned just as good using either socket type. It matters when you’re using a breaker bar where the positioning is greatly limited using a 6 pt socket. When will you be using a breaker bar? Not on tiny fasteners.
This is why starter sets have 12pt sockets for the larger ones…they will be the most useful to the beginner…
