The clearest difference is rating: Spider Evolution at 4.8 against Slime Evolution 2's 4.4. Spider Evolution also leads on review sentiment (92% vs 73%) and ratings volume (306 vs 14). Slime Evolution 2's advantage is update cadence (every 9 days vs every 6 weeks) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
