It is true that Kim Do-young's peak in the KBO is higher than Lee Dae-ho's

‌
Since there is still a long way to go in terms of cumulative stats, it's obviously not the case that he has surpassed Lee Dae-ho yet,
but if we look strictly at their peaks within the KBO, it is true that he has surpassed him.
Kim Do-young's WAR this season is higher than Lee Dae-ho's WAR during his 7-crown season.
Lee Dae-ho has a slight edge in OBP (On-Base Percentage),
but Kim Do-young is actually ahead in home runs, and especially in defense and baserunning, where he holds an insurmountable advantage.
In terms of tools that could potentially work in the Major Leagues, Kim Do-young seems to have higher potential.
