Verdict
The clearest difference is in-app purchases: DR at none against Power Save Me's 1. DR also leads on update cadence (every 6 weeks vs every 4 months). Power Save Me's advantage is ads (none vs shown) and iOS requirement (15.0 vs 18.2). On price and device support there is nothing between them.
