Verdict
The clearest difference is rating: Notevision at 4.8 against Kotobee Reader's 3.6. Notevision also leads on review sentiment (88% vs 50%) and update cadence (weekly vs every 2 months). Kotobee Reader's advantage is in-app purchases (none vs 1) and iOS requirement (13.0 vs 16.0). On price, ads and device support there is nothing between them.
