People need to stop being nostalgic, this is very good question.
Wayne is a bigger godfather to the generation that came after 05-06 (a decade now), than Snoop was to the generation that existed from 93-03, Cali nearly disappeared after Snoop. While the south and the handful of southern copies and autotune copies have been multiplying for a decade now.
This is a really tough call for me, it's hard to separate the time difference.
"He influenced Wayne, so he automatically had more influence" is weak, Weber influenced Einstein has he had more influence? Someone influenced Jesus, has that person been more influential than Jesus? Jaz-O influenced Jay-z, has Jaz-O had more influence than Jay-z?
Snoop was instrumental in commercializing gangster hiphop in 92-93 together with Dr. Dre and later on Biggie Smalls, which indirectly and directly influenced rappers. That influence is hard to compete with. Wayne has had direct influence that influenced the past 10 years. People sounding exactly like him, singer/rapper although you can't sing, auto-tune rap, tattoos and dreads, shytting out mixtapes just like him and just the type of music he made.
