Verdict
The clearest difference is in-app purchases: SkyGuardTWX at none against iFly EFB's 8. SkyGuardTWX also leads on rating (5.0 vs 4.7) and iOS requirement (11.0 vs 13.0). iFly EFB's advantage is ratings volume (353 vs 2) and update cadence (every 3 weeks vs every 3 months). On price, ads and device support there is nothing between them.
