Verdict

The call

The clearest difference is review sentiment: PDF Reader at 71% against 阅界's 53%. PDF Reader also leads on monetization model (free with in-app purchases vs paid) and iOS requirement (12.0 vs 15.6). 阅界's advantage is update cadence (weekly vs every 3 weeks). On price, ads, in-app purchases and device support there is nothing between them.
