Both of them are good though.
for example tyga really did a good job. in the song LOYAL.
while wiz-khalife did same in STARTED FROM THE BOTTOM,
but i was contemplating within me that who raps better.
i love the both of them. and there are doing there thing in a cool way.
but i want public opinion.
tyga or wiz-khalifa who raps better?

I don't even consider Tyga an average rapper. In my opinion, he's just occupying space.

Wiz K raps better

TYGA's got d sweetest flow man

Wiz khalifa
