Verdict
The clearest difference is rating: Prometheus Browser at 5.0 against Outplayer's 4.6. Prometheus Browser also leads on review sentiment (100% vs 87%) and update cadence (every 8 days vs every 3 weeks). Outplayer's advantage is ratings volume (515 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.
