Verdict
The clearest difference is ads: Zeno PDF at none against PDF Reader's shown. Zeno PDF also leads on review sentiment (84% vs 61%) and monetization model (free vs ad-supported). PDF Reader's advantage is update cadence (weekly vs every 4 weeks) and ratings volume (3.2K vs 622). On price, rating, in-app purchases and device support there is nothing between them.
