Verdict
The clearest difference is ads: Synth Sum at none against Geometry's shown. Synth Sum also leads on update cadence (daily vs every 3 months). Geometry's advantage is iOS requirement (15.0 vs 17.0). On price, in-app purchases, monetization model and device support there is nothing between them.
