I think that the following article gives a even handed view of the benefits of various types bias and straight of grain bindings.

I've seen references in this message thread, and the one the other day, about using a Clover bias tape maker to make a quilt's binding. I would ONLY use that if I did not have enough fabric to make a double fold French binding and I was unable to purchase more fabric for it. The reason is that the bias tape made with that tool will have a single layer of fabric on the quilt's edge, while a double fold French binding has two.
