I only use my walking foot when doing stitch in the ditch quilting, or other straight line quilting. It is too bulky to me to use for other stitching, it doesn't do a 1/4" seam, I would rather do free motion quilting if at all possible. Guess that means I don't love the foot, but I am glad I have it when I need it.
Another name for the walking foot is "plaid matcher" as it feeds in both layers of fabric and keeps plaids lined up so they don't get out of alignment as sewing.
