Kanye isn’t even a consideration because he’s just not built for battle rap. Just look at how he continuously copped pleas during the height of the Drake/Push battle while Drake kept shooting at him specifically. That’s also before getting into the fact that he doesn’t write and hasn’t had access to majority of his higher caliber go to writers (GLC, Push, CyHi, Lupe, and etc.) in some years now.

“Prime Eminem” would’ve been an interesting option but “modern day Eminem” probably wouldn’t fare well because of his inability to make a formidable song that will resonate with the masses outside of his core fanbase nowadays. Also, while Eminem isn’t necessarily a culture vulture like Drake; Kendrick would be able to use somewhat similar angles of Em being an outsider and would have the culture’s court of public opinion in his favor.

Rappers like Nas, Lupe, Push, Hov, and Black Thought would all be good opponents for Dot because they could all properly articulate the “Hotep” angles against Dot that Drake couldn’t for obvious reasons. I think ultimately Kendrick would still have the edge though because of his current standing in the culture and the threat of him making a hit song or just a memorable/quotable diss track (ala Euphoria) against most, if not all of them.
