Verdict
The clearest difference is in-app purchases: CFD Online Forum at none against Flight Mode Chat's 4. CFD Online Forum also leads on iOS requirement (8.0 vs 17.0). Flight Mode Chat's advantage is update cadence (every 5 days vs every 9 months). On price, ads and device support there is nothing between them.
