I do find I have much more control in handquilting and have hand quilted very elaborate designs that I would never attempt with a machine, like this dragon pictured below. I like both equally well. Machine quilting goes a lot faster than hand, that is for sure.
One thing the authors suggested when doing both is use machine quilting in borders and hand quilted motifs in the body of the quilt but that was just one application of mixing and matching the two techniques.
