Screw drivers are a tough read as to quality.
After their ability to properly fit a screw it comes down to metallurgy. Are they too soft so they round over and/or bend. or too hard where they snap off?

All the craftsman drivers I bought over the years were too soft but fortunately I took advantage of the warranty and kept swapping for new ones. Haven't found a proper brand, but I do have a miniature set of the Wiha for electronics work and they are excellent, even far better than my Xcelite (too soft).
