Different books excel in different areas: some are lauded for their prose style, others for their complex plots, still others for their social commentary or philosophical depth. Books like *Don Quixote*, *One Hundred Years of Solitude*, *Hamlet*, *The Great Gatsby*, *The Odyssey*, and *1984* are frequently cited among the greatest, but even within that list, there's no clear "winner." The "greatest" book is ultimately a matter of personal opinion.
