Verdict
The clearest difference is price: PotatoArena at Free against DEEMO's $1.99. PotatoArena also leads on update cadence (every 3 days vs every 2 months). DEEMO's advantage is chart position (#9 vs unranked) and iOS requirement (11.0 vs 15.0). On ads, in-app purchases and device support there is nothing between them.
