Verdict

The call

The clearest difference is review sentiment: WPS Office at 82% against PDF Reader's 33%. WPS Office also leads on rating (4.8 vs 3.5) and update cadence (fortnightly vs every 9 months). PDF Reader's advantage is monetization model (free with in-app purchases vs subscription) and iOS requirement (9.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
