Who's the better lyricist and why?
AZ, Lupe is too abstract at times.
Depends on what you prefer
If you're more into metaphors than Lupe
If you're more into multi-syllabic rhyming than AZ
Lupe would rank higher lyrically than most, AZ included...I haven't listened to AZ in a min (solo) but I always thought he was kinda boring/monotone, but he has his strengths.
I think seeing as how they are both technically proficient it has to come to down to who's a better song writer. I think Lu is excellent at constructing songs most of the time, even songs that I don't like are well structured and have purpose whether it be for a hit or something to be performed live.
