Verdict
The clearest difference is price: Poly 2 at Free against CR's $1.99. Poly 2 also leads on update cadence (every 4 weeks vs every 7 months) and ratings volume (686 vs 10). CR's advantage is in-app purchases (none vs 1) and chart position (#182 vs unranked). On rating, ads and device support there is nothing between them.
