OK - here goes yes you should use it for piecing at least. I have never mastered the FMQing on a domestic so I can not address that.
I used to sell Vikings and (lol) always told my quilters to use it. Of course for myself, I have always been too lazy to switch mine out. It just seemed like too much trouble. Recently ... I have been piecing lots of small things and HSTs for a scrappy quilt in between everything else. My fabric was continually "eaten" even after I tried to remember to grab the threads or use a leader. Decided to swap out the throat plate for the single hole and guess what? It works BEAUTIFULLY!
Try it and see if it improves your FMQing.
