Verdict
The clearest difference is review sentiment: Purple at 100% against Sunbeam's 70%. Purple also leads on iOS requirement (18.0 vs 26.0). Sunbeam's advantage is update cadence (every 4 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.
