Verdict
The clearest difference is in-app purchases: 建标库HD at none against PDF Reader's 5. 建标库HD also leads on iOS requirement (8.0 vs 12.0). PDF Reader's advantage is update cadence (every 3 weeks vs every 7 months) and ratings volume (8 vs 1). On price, rating and ads there is nothing between them.

On the App Store both sit at effectively the same score — 5.0 for 建标库HD against 4.9 for PDF Reader. That said, the two scores are not equally well evidenced: PDF Reader has 8 ratings behind it against 1, so its average is the more settled of the two.
