Verdict

The call

The clearest difference is in-app purchases: Service ME at none against PDF Expert's 12. Service ME also leads on iOS requirement (14.0 vs 16.0). PDF Expert's advantage is update cadence (fortnightly vs every 13 months) and ratings volume (216K vs 4). On price, rating, review sentiment and ads there is nothing between them.
