Verdict
The clearest difference is in-app purchases: Kon21 at none against TowerStacker Arcade's 2. Kon21 also leads on update cadence (every 4 days vs every 3 weeks). TowerStacker Arcade's advantage is device support (5 vs 3) and iOS requirement (17 vs 26.2). On price and ads there is nothing between them.
