I love the magic circle and use it for every project that begins in the round. It allows you to work in the center of a circle with plenty of space and then close the circle as much (or as little) as you want after you get all of your stitches in. The alternative is a chain circle where you end up squeezing all the stitches into a small space and you are left with an open hole in the center.
It may take a few tries to get the hang of it, but once you got it down, it's super easy. I don't even think about it when I do it anymore.
