Any reason one should be better than the other?

We had one where the brace went from hinge-top to lath bottom. The
joints opened up, and it sagged. So I put a wire across the opposite
diagonal, and a little tension got it back in place.

(OK, a lot of tension. Two strands, and a bit of wood wound around and
around to twist the wires.)
