Verdict

The call

The clearest difference is rating: PolyProblems at 5.0 against VAT VIP's 4.5. PolyProblems also leads on in-app purchases (none vs 3). VAT VIP's advantage is update cadence (every 3 days vs fortnightly) and ratings volume (24 vs 1). On price, ads, monetization model and device support there is nothing between them.
