I always prefer the seam rippers from Clover, either the brown flat ones or the white round-handle ones.
They have the smallest point for getting into tiny/close together stitches and have the sharpest edge, in my opinion
I have several in various locations. They are replaced a couple times a year, just like replacing needles and rotary blades, for best effect. I buy them 2-3 at a time when I can find them on sale or at a good price. They are my favorite stocking stuffer.
