Verdict
The clearest difference is review sentiment: KAYO at 100% against Citadel Team's 51%. KAYO also leads on rating (3.0 vs 2.6) and update cadence (monthly vs every 2 months). Citadel Team's advantage is ratings volume (10 vs 1) and iOS requirement (13.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.
