Verdict
The clearest difference is review sentiment: Formatter at 100% against JSON Viewer's 6%. Formatter also leads on price (Free vs $1.99) and rating (5.0 vs 4.2). JSON Viewer's advantage is ratings volume (113 vs 2) and update cadence (fortnightly vs every 2 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
