It depends on what I am sewing. I never do a scant 1/4" as I found that with the thread I use and the presser feet I use, I don't have any need to.

For a regular 1/4" seam in sewing pieces/blocks together I use a 1/4" presser foot as my guide.

For sewing diagonally on small pieces for HST or the like or sewing strips/sashing/binding together for length, I use the tape I keep on my machine that has measurements and lines on it for sewing a straight line, so I don't have to draw a line on the fabric for a diagonal seam.

For sewing down edgings, like for sewing down the final side of top sashing when doing QAYG sashing, I use a narrow presser foot, as it gives me a 1/8" seam line. And I also use this 1/8" presser foot for sewing down applique edging.

For sewing down the first side of the binding, I use a 3/8" presser foot as I like a wider binding and then when I flip the binding over, I switch to the narrow presser foot as it gives me a 1/8" seam line on the edge.

The presser feet that I use, are accurate for the measurements that I want, with the thread I use. It took me a bit of searching to find the ones that had accurate measurements that fit my machine, especially the 3/8" one, but now I'm good.

My presser feet are accurate on both sides of the presser feet prongs or tongues, so I can feed my fabric through on different sides of my machine 'throat' if I need to. Except for the 3/8" one and I was able to find both a left and a right 3/8" presser foot so I just switch them out of I need to feed my fabric though on the other side of the throat area.
