Verdict

The call

The clearest difference is review sentiment: PowerX at 45% against e's 5%. PowerX also leads on update cadence (fortnightly vs every 11 months). e's advantage is monetization model (free vs ad-supported) and iOS requirement (16.4 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
