Verdict
The clearest difference is in-app purchases: OpenDocument Reader at none against PDF Pro's 12. OpenDocument Reader also leads on update cadence (every 4 weeks vs every 2 months) and iOS requirement (15.0 vs 17.0). PDF Pro's advantage is ads (none vs shown) and review sentiment (60% vs 30%). On price and device support there is nothing between them.
