"I'll take a manuscript laid out by a professional any day of the week."

LaTeX with a good template looks much better than some of the "professional" work I've seen.

Also: the real question here is whether the "professional" layout adds enough scholarly value to make it worth paying the outrageous journal subscription price.

Journals are not intended to be aesthetic experiences. That is not their purpose. Their purpose is to disseminate knowledge. High prices are counterproductive to that goal.
