Verdict
The clearest difference is rating: Draft Paper at 4.4 against Model Scaler's 2.9. Draft Paper also leads on update cadence (every 2 weeks vs every 6 months) and ratings volume (16K vs 12). Model Scaler's advantage is in-app purchases (none vs 1) and iOS requirement (9.0 vs 15.0). On price, ads and device support there is nothing between them.
