Those 3 types of water supply line have their own problem while using it. The chrome plated brass one is more difficult to use than flexible supply line, caused by the brass using.
On the other hand, each toilet supply line types has to be set with a right way. For example while tightening the leaking one. When you tighten it so hard, which with a non-recommended power, it will cause the larger leak than it needs. It also being considered for other supply lines.
