We have a task to statistically identify which data set is more reliable among the two sources.

Case background: Design function releases drawings and let's treat them as specs/ master data

Data set1: same set of drawings but with some mismatches
Data set 2: same set of drawings but with some mismatches/ additions

For the purpose of this study, we have 50 data points each, and we can identify how many percentage points set1 and set 2 match with master data. I could simply select the set with higher matches but we want to use hypothesis test to prove which data set is better. Can you help me in choosing right test/ tool for this
