There probably is some difference in quality, I've only used good ones.
Not sure bout the strings quality probably depends on the quality control of the manufacturer. I assume there shouldn't be much variation in a single string due to the materials and winding being constant, but hey things sometimes slip through QA.
Accuracy with digi calipers does depend on quality and the condition of the instrument itself;
- clean, undamaged jaw ends/faces
- slideways not worn, dirt free, not too tight or too loose
Also, using a consistent "touch" when measuring. You can vary your measurement by pressing too hard.
