Verdict
The clearest difference is review sentiment: Time at 100% against PDF AutoScroll's 56%. Time also leads on rating (5.0 vs 4.3) and price ($1.99 vs $5.49). PDF AutoScroll's advantage is update cadence (every 2 weeks vs every 14 months). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
