I wouldn’t open carry anyway but one advantage I see is not worrying about ‘printing’ or your shirt riding up exposing your piece as you bend over or reach for something.
I recently moved.
In my previous state, you could open carry without permit or concealed carry with permit but if you concealed, you were not allowed to print without risk of losing you concealed carry permit. State law let you open carry almost anywhere and the law prevented local authorities from bothering you.
In my current state, you can legally open carry but will likely get hassled if you are in the urban regions. If you have a concealed carry permit, you can print all day with no repercussions.
A minor difference but seems strange.

Excellent point.
