Alright, although it's a rather moot point for the simple fact that music especially rap music, is subjective.
I personally don't think Kendrick's verse was the best on the album. It was a great verse, and the picture that he painted of himself chasing "The Life" that inhibits Drake was awesome. I really dug it. But I skip it every single time. It doesn't fit on the album at all. I have no idea why Drake attached that to Marvin's Room to be honest. It would have been great if it was just Kendrick's track on some other project. On Take Care? Not so much. Just because he "used personification" doesn't make his verse "that" extraordinary. It was just good to me.
What I'm getting at is that while Kendrick did showcase an excellent use of Personification, and overall churned out a great verse, it wasn't the best verse on the album. The Ride, Drake on Lord Knows, the first verse on Headlines, and some other Take Care cuts that weren't on the album (But recorded for take care, ala free spirit, dmcb) were better than that.
I also think Drake is an extremely underrated lyricist and prefer his raps instead of Kendrick's on almost all occasions, but that's besides the point.
