Verdict
The clearest difference is rating: The Tech Deck at 5.0 against McMaster's 4.3. The Tech Deck also leads on update cadence (every 5 days vs every 5 weeks). McMaster's advantage is ratings volume (220 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
