In my opinion both of 'em haven't lived up to the hype after their last works.
Mac's 'Best Day Ever' mixtape was allright but it definitely wasn't K.I.D.S. material IMO. And of course Wiz has gotten a lot of criticism after dropping and leaking the 'Rolling Papers' album. Mac has gotten more popular after dropping 'Donald Trump' on youtube, made it on MTV for the first time last week. Was a participant in last week's 'Freshman of the week' section from the MTV site if I remember correctly. Of course both Wiz and Mac have been featured in XXL Magazine.
