New Point: I have both and I don't like the 57 because I tend to butt my fabric against it which doesn't give me the scant 1/4 that works best for me. Sometimes, if I am not careful, that foot results in "La GRAND 1/4 inch." I find the 37 where I can see if I am "shoving" the sewing to the side too much as it peeks out, is the best foot for my use. I NEVER use the 57 anymore since I have found I have this problem. Test Drive both is good advice! And take some of your own scraps so it will be a true test.
