One downfall of the foot with a guide is that the fabric can sometimes go underneath the guide without your even knowing it. That defeats the whole purpose and messes up the seam allowance. If you're not aware that the guide isn't working, you may never know why things don't line up right down the road. Fabric never slips under moleskin, guaranteed!
I bought 2 different feet (reg shank and slant shank) and did not like them for the same reason as posted here. Also, as a PP stated, it's hard to sew if you like to use pins because they get caught on the guide edge. I took a pair of pliers and took both of the guides off.
I like Bonnie Hunters method of creating a scant 1/4" seam because it won't ruin the bed of my vintage/antique machine.
Good luck and enjoy making your first quilt!
