Verdict
The clearest difference is rating: Book Towers at 4.8 against Dooru Library's 4.2. Book Towers also leads on update cadence (every 2 weeks vs every 5 months) and review sentiment (87% vs 73%). Dooru Library's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price and device support there is nothing between them.
