We are as subjective about the people that do the games as the people that play them. We either like them or we don't.
However, with my broadcast experience of 25 years, just from the viewpoint of doing the job right as it was originally designed, Aikman and Buck are the gold standard. I don't care whether people like them or not, they do the job better than all of the others because first and foremost, you do not have to work to hear them. Projecting their voices without yelling is job 1 and they're both very well trained at that. Michaels is right there with Buck. I don't really care for what Daryl Johnston has to say most of the time but he is very good at saying it. He responded to the training as well as Aikman did.
When they tried Aikman out in his first gig, Europe, they were really surprised because his broadcast voice was not his natural. He's pretty soft spoken, not as raspy as Romo, but he used proper technique to project his voice and created more energy. He learned to be a broadcaster just as he had being a QB, proper mechanics and technique.
Aikman treats broadcasting as more of a science and Romo treats it as art, just as they did the QB role.
