Verdict
The clearest difference is update cadence: KTuner FlexFuel at daily against xDelete's every 10 days. KTuner FlexFuel also leads on rating (5.0 vs 4.7) and iOS requirement (11.0 vs 15.0). xDelete's advantage is ratings volume (501 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
