Verdict
The clearest difference is in-app purchases: CortexQuest at none against World Quiz's 1. CortexQuest also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). World Quiz's advantage is chart position (#36 vs unranked). On price, device support and iOS requirement there is nothing between them.
