Verdict
The clearest difference is rating: uDisk at 4.3 against Power Reader's 3.8. uDisk also leads on review sentiment (84% vs 55%) and ratings volume (247 vs 4). Power Reader's advantage is in-app purchases (none vs 1) and iOS requirement (8.0 vs 11.0). On price, update cadence, ads and device support there is nothing between them.
