The real dif between Jericho vs. Miz is that Jericho actively understands what could get him cheered for and rejects it. Hence no more cute catch phrases and funny jokes/sarcasm. He knows how to be a heel that gets heat and only heat. Miz however wants to be the "cool heel" and adds the flourishes Jericho purposely removed from his act once he went heel and dropped the Y2J persona. That Jericho still gets cheered is just a testament to his prior face connection with the fans.
