Verdict
The clearest difference is review sentiment: PDF Tools at 100% against Acrobat Reader's 49%. PDF Tools also leads on rating (5.0 vs 4.6) and iOS requirement (13.0 vs 18.3). Acrobat Reader's advantage is update cadence (every 9 days vs every 16 months) and ratings volume (654K vs 11). On price, ads, in-app purchases and monetization model there is nothing between them.
