Verdict

The call

The clearest difference is ads: AI Office at none against PDF Reader's shown. AI Office also leads on ratings volume (383 vs 4) and device support (3 vs 1). PDF Reader's advantage is update cadence (every 4 days vs every 2 weeks) and review sentiment (50% vs 36%). On price, rating, in-app purchases and iOS requirement there is nothing between them.
