Its kinda of a toss up to me. Skylar is 10x more annoying then Carmella. From her holier than thou attitude when Walt was trying to provide in dire circumstances to actively cheating/shytting on him, she is much more of a bytch then Carmella(who rightfully had an issue with Tony) But AJ is much more of a fukk boy then Walt JR. Yea Jr is an smart ass despite the disability, but AJ has to be the most lamest, corniest son in TV history outside Eddie Winslow. The kid had everything in the world going for him and was still a loser. Kid couldn't ever commit dat properly
