I agree with quiltmaker. I never bother with scant ¼" seams. Don't see any reason to. As long as the seam allowance is consistant throughout the quilt, the only difference a scant seam will make is in the final overall dimensions.
Using the edge of my ¼" foot makes for extreme accuracy in the seams, dead-on matches, flat tops and squared corners. It is also stress-free, much easier to align, and more fun in the making. Having a final size that exactly matches the original design just doesn't matter to me. If it needs to be larger (it's never off by much more than an inch each way), I just increase the width of the outer border.
