Verdict

The call

The clearest difference is price: Comet at Free against OpenWebUI's $2.99. Comet also leads on rating (4.8 vs 4.0) and ratings volume (7.8K vs 3). OpenWebUI's advantage is in-app purchases (none vs 3) and chart position (#92 vs unranked). On update cadence, ads, device support and iOS requirement there is nothing between them.
