YUIDoc excels in the accessibility of the stock themes that it provides. The output is readable, searchable, and is user-friendly, even for non-technical users. JSDoc, on the other hand, provides nothing more than an output of all the API objects in a linear way. This makes it harder for non-technical users to find information and make full use of the output. Everyone loves good designs, and it is essential that the generated documentation looks clean and is accessible. Doxx, Docco, and YUIDoc have an edge here for producing neat outputs that look beautiful out of the box.
