My #20 foot with the needle one click to the right is far more accurate for a scant ¼" than either the #37 or #57 foot (the dedicated ¼" feet). The open toe gives a much better view of where the needle is going, plus both feed dogs are fully underneath the fabric so it feeds evenly resulting in more accurate seams. With the ¼" feet, the right feed dog is pretty much useless and the fabric steers to one side because of it.
