Verdict
The clearest difference is price: Encode at Free against Learn React.js's $0.99. Encode also leads on update cadence (every 2 weeks vs every 15 months) and ratings volume (6.4K vs 7). Learn React.js's advantage is in-app purchases (none vs 2) and ads (none vs shown). On device support there is nothing between them.
