Verdict
The clearest difference is rating: Prometheus Browser at 5.0 against Loud's 4.5. Prometheus Browser also leads on iOS requirement (18 vs 26.0). Loud's advantage is in-app purchases (none vs 1) and update cadence (daily vs every 8 days). On price, ads and device support there is nothing between them.
