I often use a decorative stitch on a baby or child's quilt for durability. When I do I like a serpentine or some stitch with some movement as it can camoflage any deviation from trying to get a real straight stitch when binding. If I use too much of a decorative stitch, it gets stiff and I don't care for that. Just my opinion - again, no quilt police here so do what works for you.
