I have had both, embroidery only and combination machines. I personally prefer the combination embroidery/sewing/quilting machine. I actually sold my Brother embroidery stand alone machine. I really think it comes down to personal preference. If you embroidery only, then the embroidery machine is your best. Yet, if you do more like quilting, sewing and embroidery then you may want the combo. There is no difference in the stitching to my knowledge. As I had all three machines running on the same projects and all nice quality stitches. That is with a Janome and a Brother & Babylock running side by side. I think you get more bang with your buck with the combo machines. Just my two cents worth anyway. I love to embroidery but quilt also. Do what works for you.
