How to say "unparalleled" in Japanese

• 無二むにCommon
  no-adjectiveCovers the core sense of being without equal: a person, work, or achievement that has no rival. Use it when praising unmatched talent or quality — the direct equivalent of calling something peerless or matchless.
• 不世出ふせいしゅつCommon
  nounStresses rarity as much as greatness: its like appears in the world only once in a great while. Suited to extraordinary genius or historic stature rather than ordinary comparisons of quality.
• 極まりないきわまりないCommon
  suffix, i-adjectiveCovers a different sense: a quality or behaviour carried to an extreme, as in rudeness that knows no bounds. Not for praising someone as peerless — use it only when 'unparalleled' means 'in the extreme'.

  The desk is in a state of total disorder.

Choose 無二 for someone or something with no equal at all, 不世出 for extraordinary figures whose like rarely appears in the world, and 「極まりない」 when a quality such as rudeness is extreme beyond bounds.
