Verdict
The clearest difference is in-app purchases: Sumthing at none against KenKen Classic's 6. Sumthing also leads on ads (none vs shown) and update cadence (daily vs every 4 months). KenKen Classic's advantage is ratings volume (3.2K vs 3) and iOS requirement (12.1 vs 15.1). On price and device support there is nothing between them.
