Verdict
The clearest difference is review sentiment: DOPE at 100% against BulletDrop+'s 51%. DOPE also leads on rating (5.0 vs 3.9) and update cadence (weekly vs every 4 months). BulletDrop+'s advantage is ratings volume (83 vs 4) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
