They're all great albums but I think we have to wait until at least 2030 to see if they're classics or not because it's easy to live in the moment and call any quality album a "classic" in an era where they come so scarcely compared to the past.
However, this discussion has sparked an interesting debate over whether quality albums that lack impact/influence can be called classics or not.
Put it this way. If KD2, KD3, or Magic are classics, then you'd realistically also have to consider albums like Alfredo, Pray For Haiti, It's Almost Dry(which actually went number 1 despite low sales), Scaring The Hoes, A Written Testimony, Cheat Codes, and Melt My Eyez "classics" too since they're also great/quality hip hop albums that came out this decade.
Now, do you see how far the rabbit hole can go when you loosen the "classic" label in that way.
There's nothing wrong with an album simply being great or high quality. Not every album needs to be touted as a classic to be held up in high regard. Nas has been having an amazing run at his age. Many other rappers in his age range have either fallen off(Em, Ye), are on a hiatus(Jay), or straight up irrelevant musically(50, Snoop).
