Verdict
The clearest difference is review sentiment: PDF Reader at 61% against Shark Scan's 25%. PDF Reader also leads on rating (4.8 vs 4.3) and ratings volume (3.2K vs 105). Shark Scan's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.
