Verdict

The call

Epub Reader and TecViewer both sit at 4.5 stars, but that hides the real split: 98% of TecViewer's written reviews are positive against 55% of Epub Reader's. Epub Reader's advantage is ratings volume (11K vs 27) and update cadence (every 2 weeks vs every 6 weeks). On price, rating, ads and in-app purchases there is nothing between them.
