Verdict
The clearest difference is in-app purchases: Quantum AI at none against AI Chat Assistant's 16. Quantum AI also leads on ads (none vs shown) and update cadence (every 4 days vs fortnightly). AI Chat Assistant's advantage is chart position (#38 vs unranked). On price and device support there is nothing between them.
