1. You can change the needle plate with just a press of a button instead of screws.
2. Snap on Acufeed feet - standard, 1/4 inch, stitch in the ditch
3. 9mm stitch width
4. More alphabet options.
I do piecing, free motion quilting, stitch in the ditch, and machine applique. I can make the changes on this machine quickly to go from one to the other. I have had no problems with the tension for free motion quilting - even with metallics and monofilaments. The stitches I use for applique lay flat and tight. I have used the fine Bottom Line threads to the coarser/heavier quilting threads and the automatic tension seems to adapt.

Hope this helps.
