Verdict
The clearest difference is rating: SuperBand at 2.6 against KDultra's 1.0. SuperBand also leads on ratings volume (56 vs 1) and review sentiment (17% vs 0%). KDultra's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.
