The clearest difference is update cadence: McMaster at every 5 weeks against 3M Electrical's every 6 months. McMaster also leads on ratings volume (220 vs 4) and review sentiment (68% vs 50%). 3M Electrical's advantage is iOS requirement (10.0 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.
