Agree about Ambrose. He's awful in the ring and for a supposedly great promo I've never been captivated by his mic-work.
Though, I prefer Reigns over Ambrose and Rollins. Rollins has had a pretty terrible title run that seems to be immune from criticism around here for some reason.
People try to rationalize his title run by saying he's a classic heel but having J&J Security get wins over you while World Champion is inexcusable. The only great moment he's had while Champion is his ladder match with Ambrose. And honestly that match was way too long.
