Verdict

The call

CLASS101 and 클래스유 both sit at 4.6 stars, but that hides the real split: 86% of 클래스유's written reviews are positive against 39% of CLASS101's. 클래스유 also leads on update cadence (every 4 days vs every 3 weeks). CLASS101's advantage is ratings volume (546 vs 27). On price, rating, ads and in-app purchases there is nothing between them.
