Verdict
The clearest difference is in-app purchases: KeyStorage at none against PDF Scanner's 4. KeyStorage also leads on rating (5.0 vs 4.6) and update cadence (every 3 weeks vs every 2 months). PDF Scanner's advantage is ratings volume (45 vs 1). On price, ads, device support and iOS requirement there is nothing between them.
