I don't know about the others, but the Big Foot has been my FMQ foot for quite some time, and I love it. Would really prefer an all metal one (since the Big Foot was to replace a cheap FMQ off brand foot that snapped--literally!), but the Big Foot is great. Have you done FMQ before? The BF can be a little intimidating because it makes a lot of noise, but it really helps to time your movement with the quilt top.
