I happened to get both for my little Viking when I bought the Quilting Kit for it. I started practicing my free-motion quilting with the open toe, but since I'm very new and still have a tendency to get long stitches and my movement isn't smooth yet the open toe kept getting caught in them. I decided to practice using the closed toe foot to minimize my frustration, even tho I like being able to see with the open toe foot. JMHE :-)
