Verdict
The clearest difference is in-app purchases: BooTap at none against Slime Evolution's 4. BooTap also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). Slime Evolution's advantage is iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
