Multicoated, vs. Single Coated Enlarging Lens?

[John Layton]

A good lens designer will tailor lens coatings (multi or otherwise) to integrate with and support the design parameters of a given lens. In other words, multiple coats don't always equate to "better" performance. Leica comes to mind as a company who's been quietly multi-coating many of their lenses for years, but only when this makes sense to the specifics of the design and intended uses of the lens in question.

Yep. It's not necessarily a matter of better or worse either. Sometimes I prefer the slightly gentler rendition of a single-coated taking or enlarging lens for color work in particular.
