Verdict
The clearest difference is in-app purchases: Synthesis24 at none against King Math 24's 4. Synthesis24 also leads on ads (none vs shown). King Math 24's advantage is update cadence (every 2 months vs every 6 months) and iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
