I don't use any foot with a guide on it, especially a quarter inch foot.
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!
