Verdict

The call

The clearest difference is rating: PDF Converter at 5.0 against PDF Reader's 4.5. PDF Converter also leads on update cadence (every 3 weeks vs every 2 months). PDF Reader's advantage is ratings volume (3.5K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
