Verdict

The call

The clearest difference is review sentiment: 執筆忘字 at 83% against MERS.HK's 40%. 執筆忘字 also leads on update cadence (every 2 months vs every 5 months). MERS.HK's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.
