### Which charge is more favorable?

Between these two drawings of Lewis Structures, would it be more favorable to draw the structure so that there is a -1 charge on 2 of the O's and a 0 formal charge on the central atom, S or would it be better for all the O's to have a FC of 0 and then S to have a charge of -2? I’m not sure if there is a rule about charges on the central atom.

I was told the goal is to have all the atoms with a charge between -2 and 2 (so only -1,0,1), so I think having a -1 charge on two atoms would be better than -2 on one.

Having multiple -1 charges are better than a single -2 charge.
