Verdict
The clearest difference is price: Angelology at Free against Java大全's $1.99. Angelology also leads on rating (5.0 vs 4.5) and update cadence (every 10 days vs every 31 months). Java大全's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
