nas is/was not as technically savvy on ether.
that is also, why it resonated for him as he goes out of his comfort zone.
az, when battling and nas are two different artist technical skillwise.
as az, keeps his airtight technical rubrick battling.
while, alternatively and oddly nas is way more loose with his style and technical skills in battling.
you, can easily see a difference in nas and az battling and what they do.
there is no way az wrote ether.
as, ether has no technical rubrick that is close to az's skill set.
ether, is effective because nas was loose and let his emotions handle any technical stylings he did not typically use/employ bar to bar.
also, when nas battles he is emotionally charged with anyone he disses, and abandons his technical rubrick like kn don't body ya self and ether.
While, az always sticks to his rubrick.
showcased on his diss to fiddy, incomparison to don't body ya self.
