Verdict
The clearest difference is ads: HERO at none against Overdrive II's shown. HERO also leads on rating (4.4 vs 4.0) and review sentiment (80% vs 57%). Overdrive II's advantage is update cadence (every 6 days vs every 4 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
