Verdict
The clearest difference is in-app purchases: SkySling at none against ONOMATOPIA's 15. SkySling also leads on ads (none vs shown) and update cadence (daily vs every 10 days). ONOMATOPIA's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 26.2). On price there is nothing between them.
