Verdict

The call

The clearest difference is rating: Smallpdf at 4.8 against PDF Reader's 4.3. Smallpdf also leads on update cadence (every 9 days vs every 2 months). PDF Reader's advantage is in-app purchases (none vs 11) and review sentiment (77% vs 68%). On price, ratings volume, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Smallpdf holds the better App Store score, 4.8 against 4.3. Both are backed by a comparable volume of ratings — 3.9K and 6.9K respectively.
