Verdict
The clearest difference is in-app purchases: Ristoo(客户) at none against PDF Watch Viewer's 5. Ristoo(客户) also leads on iOS requirement (10.0 vs 26.0). PDF Watch Viewer's advantage is update cadence (every 5 days vs every 8 months). On price, ads and device support there is nothing between them.
