Verdict
The clearest difference is price: TWB学术电子书 at Free against ChmPlus Pro's $6.99. TWB学术电子书 also leads on rating (5.0 vs 2.7). ChmPlus Pro's advantage is update cadence (every 9 days vs every 2 months) and ratings volume (9 vs 1). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
