Verdict

The call

The clearest difference is rating: CamScanner at 4.8 against PDF Reader PDF Viewer's 3.0. CamScanner also leads on ratings volume (1.9M vs 2) and update cadence (weekly vs every 3 weeks). PDF Reader PDF Viewer's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.
