I put "I don't really care one way or another", but for me, it's more that I don't really have any strong connection to any of the origin companions, so what class they are just doesn't matter for me. That said, because I sort of know them a bit, I can't really think of Gale as NOT a wizard, or Shadowheart as NOT a cleric, and so I'll probably keep them as they are, but I have absolutely no objections to others changing them. I do respect the "too much freedom can be a bad thing" argument, but in this case it doesn't affect my gameplay experience.
