Verdict
The clearest difference is in-app purchases: Capacity at none against AI Code Builder's 10. Capacity also leads on device support (3 vs 1) and iOS requirement (15.1 vs 18.0). AI Code Builder's advantage is update cadence (weekly vs every 3 months). On price and ads there is nothing between them.
