Is Krein's D2 heat-treat as good as Dozier ?

Hi
Is it as good?

And why do they use D2 most of the time?

I would assume it could be as good because Krein used to work for Dozier. I think the reason Dozier uses a lot of D2 is because he's mastered it's HT in a way that the edge retention of his D2 is some of the best in the knife business.
