Verdict

The call

The clearest difference is ads: PDF Reader at none against Epub Reader's shown. PDF Reader also leads on rating (4.9 vs 4.5) and review sentiment (71% vs 55%). Epub Reader's advantage is ratings volume (11K vs 8) and chart position (#132 vs unranked). On price, update cadence, in-app purchases and monetization model there is nothing between them.
