Verdict
The clearest difference is price: RatNest at Free against JSON DevKit Editor's $0.99. RatNest also leads on in-app purchases (none vs 3) and update cadence (daily vs every 9 days). JSON DevKit Editor's advantage is device support (3 vs 1). On ads and iOS requirement there is nothing between them.
