Verdict
The clearest difference is in-app purchases: PlasticList at none against Custom Rings's 1. PlasticList also leads on rating (5.0 vs 4.8) and iOS requirement (15.1 vs 17.0). Custom Rings's advantage is update cadence (every 4 days vs every 3 weeks) and ratings volume (6 vs 1). On price, ads and device support there is nothing between them.
