Nana up north;
I have heard this same information and I agree with it but so many people are afraid of anything that resembles 'bias'. Everyone should try a small sampler sandwich with bias binding just to try it and practice it.
One other thing that I learned right here on the QB is to not press the binding in half before you sew it to the quilt.
Just simply lay the two raw edges together as you align them on the edge of the quilt and sew them down.
I love this and never have a crease to deal with to get in the right place. Binding turns to the back easily and looks great!
peace
