Verdict
The clearest difference is review sentiment: Crait at 81% against 默信's 17%. Crait also leads on rating (4.7 vs 2.4) and ads (none vs shown). 默信's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (fortnightly vs every 2 months). On price, in-app purchases and device support there is nothing between them.
