Verdict
The clearest difference is rating: xDelete at 4.7 against Fuel's 3.1. xDelete also leads on update cadence (fortnightly vs every 10 months) and review sentiment (73% vs 50%). Fuel's advantage is monetization model (free vs paid) and iOS requirement (13.4 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
