I find Brandel insufferable. All this talk about "not afraid to call players out" and "speaking his mind" really isn't my primary dislike about him. It's just that it's the only schtick he has. He's a one-trick pony. He used to be somewhat appreciable back in his early days on the network, back when he would talk about actual golf stuff that was informative.
He carries a chip on his shoulder. He's surrounded by former players/analysts (David Duval, Frank Nobilo) who've enjoyed reasonably successful careers as players, and it's obvious that deep down he resents the fact that he was basically a nobody in his playing career. It's plain as day, and the only way he can compete with their veteran knowledge is by doing what he does - making a name for himself as the network's biggest shitweasel.
