To me the film grain gives a picture substance. I like that, which is why I enjoy making prints from 35mm negatives.
Tri-X 400 grain from 35mm looks very good.
But then again, it isn't that important either. It always starts with a good picture, in my opinion; there is nothing more dull than a photograph that gives me no emotional reaction, and that is printed to perfection. But a jewel of a print is one where I really get into the story, and the grain and all that becomes immaterial, far beyond the point where I care.
But to harmonize with the OP's post, I rather take a print with visible grain than one without. I think it's something subconscious at work.
