I do find the silver dials to be a bit sterile. I have a MUT Moon, which I bought nearly a decade ago, and even I find it cold every now and then. The black dials, however, I find to be charming* and unassuming.
Under either circumstance, silver and black dials are both interesting. And, as Juliosotto mentioned, the black dial in particular is the dress watch equivalent of the Explorer 1.
