Verdict
The clearest difference is rating: Fraction Print at 5.0 against McMaster's 4.3. Fraction Print also leads on review sentiment (100% vs 68%) and update cadence (weekly vs every 5 weeks). McMaster's advantage is ratings volume (220 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.
