I'll buy that Drake got him on Fuckin Problems, but Kendrick won on Poetic Justice and Kendrick has the best verse on Drake's whole album.
I agree that Drake is probably a more versatile artist and he has many more quotables (You can't go ten minutes without someone reciting a Drake line), but Kendrick has more technical ability (flow, rhyme schemes, etc..)
Drake kinda phoned it in on Poetic Justice but Kendricks verse was terrible. You really liked that?
