Verdict

The call

The clearest difference is ads: What Dragons Know at none against Octopus Evolution's shown. What Dragons Know also leads on rating (5.0 vs 4.8). Octopus Evolution's advantage is ratings volume (4.1K vs 1) and update cadence (every 6 weeks vs every 5 months). On price, in-app purchases, monetization model and device support there is nothing between them.
