No one has mentioned the biggest (by quantity) RPG-based novel line—namely, Forgotten Realms. Probably because of its reputation for iffy quality. But I think it depends on whether “the best” in this case means the mean average quality of all books published in the line, or just the quality of the, say, top 10 percent of the books in the line.
If it’s a mean average situation, Forgotten Realms will not get high marks, because there are so very many poor FR novels. But the thirty or so best FR novels, in my opinion—that is, the top 10 percent—range from pretty good to really great.
