There are some industry standards. Usually ENG cameramen never use monitors. It takes skills, but normally people hardly ever screw it up. Look at major TV network – there is no monitors there except for the studio work.
Production houses often use monitors. Director, producer and probably the customer, all want to see the picture on the monitor to make sure the cameraman knows what he is doing. It makes some creative opportunities as well, like little brain storms on the shoot, etc.
