Each sewing machines are made for different purpose. I use a Pfaff for my regular construction sewing, Brother embroidery machine, featherweight for quilt piecing, Bernina for quilting, old commercial Singer for heavy duty sewing and quick sewing. Several others for general sewing, plus 2 treadle sewing machines I use for fun. I'm not sure if one machine is better than the other as I have never had problems with any of them, except a Singer that I purchased years ago, couldn't keep it in time when I sewed denim jeans. I usually buy the top of the line as they get dated real soon. I feel the newer machine are likely to have more problems because they do so much more than the old metal machines that just ZZ. I feel keeping them clean, changing needles and general maintenances any machine will last long time.
