Unlike a lot of people, my idea of "looks best" depends on practical
things, not silly rules. If you plug something into the top outlet (of a

bottom outlet making it harder to use.

I'm not sure if I EVER thought it looked best to use the top.

Just wrap electrical tape around the hot terminal on all plugs!
