Verdict

The call

The clearest difference is review sentiment: PDF Reader at 81% against PDF Scanner Pro ⊟'s 40%. PDF Reader also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). PDF Scanner Pro ⊟'s advantage is update cadence (fortnightly vs every 2 months) and rating (4.7 vs 4.5). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

PDF Scanner Pro ⊟ holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 3.5K and 6.1K respectively.
