Swan Song, I don't know what brand your machine is or where you plan on purchasing the foot but some places will let you "test drive" and compare. You might call ahead and take a couple small blocks that you could repurpose into potholders or something to see which one you really like. I find that I will sometimes like something because it suits my purpose. Both those feet have larger openings so you should be able to use wider stitch widths with them. That means it would be a plus for anything like heirloom sewing, piecing batting together, etc. So it might come down to whichever one allows to to see the most comfortably and that is a personal choice.
