Verdict

The call

The clearest difference is in-app purchases: 7788旧书 at none against 当当's 10. 7788旧书 also leads on iOS requirement (11.0 vs 15.0). 当当's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 9 months). On price and device support there is nothing between them.
