Verdict
The clearest difference is ads: ACA2000 at none against NAVER Dictionary's shown. ACA2000 also leads on monetization model (free vs free with in-app purchases). NAVER Dictionary's advantage is review sentiment (35% vs 27%). On price, update cadence, in-app purchases and device support there is nothing between them.
