If you just want to show your muscles, the white one will show your muscles. The black one is slender. If you are tall and a little burly, the black one looks better. However, if white is left for a long time and is not well maintained, the surface will be oxidized and yellow, which is particularly ugly. If you get something that can't be washed, you are in trouble. Buy black and you won't have these troubles. It's just your personal opinion.
