Verdict
The clearest difference is review sentiment: Merge & Split at 100% against PDF Expert's 46%. Merge & Split also leads on monetization model (free vs free with in-app purchases) and rating (4.9 vs 4.7). PDF Expert's advantage is ratings volume (216K vs 16) and update cadence (fortnightly vs every 6 weeks). On price, ads, in-app purchases and device support there is nothing between them.
