Verdict
The clearest difference is review sentiment: Device Lab at 95% against POWER's 0%. Device Lab also leads on rating (5.0 vs 1.0) and ratings volume (24 vs 4). POWER's advantage is price (Free vs $3.99) and iOS requirement (15.6 vs 17.0). On update cadence, ads, in-app purchases and device support there is nothing between them.
