I've not had a braided line fail. The installation is less prone to DIYer error than stiff pipes.

I've had several of them fail, usually at the crimped end. It is true that they are easier to install but since he already has an installed solid pipe he doesn't need to go through the pipe bending and cutting process if the leak is from the connector and not the pipe itself.
