The clearest difference is in-app purchases: Checklist at none against Second Brain AI's 3. Checklist also leads on device support (4 vs 2) and iOS requirement (12.0 vs 17.6). Second Brain AI's advantage is update cadence (every 5 days vs every 8 months). On price and ads there is nothing between them.
