It wouldn't be better necessarily. Generally you want to get the opinions of multiple doctors and do your own research and use your own judgement in evaluating the advice you're getting. The point is that in the face of such enormous complexity the difference between a layperson with a rudimentary understanding of biology and your average doctor is not much. The difference is more pronounced when you're talking about people who are in the very top of their field but those people tend to be quite open minded and curious in my experience. They have such depth of knowledge that they are aware of how little they know.

It's also important to distinguish between technique and knowledge. The difference between a layperson and their surgeon is enormous, a layperson and their doctor, not so much in the grand scheme of things.
