Verdict

The call

The clearest difference is in-app purchases: CEO서평 at none against SERIES's 15. CEO서평 also leads on ads (none vs shown) and iOS requirement (14.0 vs 16.0). SERIES's advantage is update cadence (every 3 weeks vs every 5 months) and chart position (#75 vs unranked). On price and device support there is nothing between them.
