I have the foot with the guide. I love it. I usually forget to adjust my needle position for a scant 1/4 seam but it helps me be consistent so when I'm not sewing anything that requires a scant seam I'm good. It took time but now I don't smash my fabric up against the guide. I more or less use it to keep myself in control so I'm not ripping out a thousand wobbly seams lol.
