As a total beginner, I can't compare to other brands. What I can say is I didn't accidentally cut myself with those, even when using my non-dominant hand, and they cut fine—as long as you cut firmly. If you're too gentle, you might not cut your cuticle all the way through, and the work is so precise that when doing your second corrective cut, you might leave a messy dangling bit. But as you can tell from the picture, even with this slight struggle, you'll still make it look clean in the end. Be patient, and make strong cuts once you have the right angle!
