Both the Theories of Intelligent Design and Evolution are theories.
This is incorrect. In scientific terminology, a theory is a testable model, one that has reached a very reliable level of sophistication. The Theory of evolution has reached that level because of hundreds of years of research and thousands of fossil and biological evidence that supports it. Intelligent Design is not a theory in the scientific sence because it is not founded on any empirical evidence, makes no predictions, and in no way leads to an informed understanding of the natural world. It is incorrect to use the term 'theory' for what is actually a different philosophical position.
I agree that the central difference between ToE and ID are perspectives and worldview. If someone believes that wonderment and marvel and fervent wishing are a valid basis for establishing models of understanding, then they are more than welcome to exist in their own circles. However, to impose this viewpoint into the realm of Science accomplishes nothing.
