I very much so liked Nashor's Tooth on Diana, but it accomplishes a completely different goal than Lich Bane. Nashor's is a great farming and splitpushing tool, and is better on Diana for damage to champs if you build her as a bruiser. Lich Bane is a single target burst tool, and is better if you build her as an assassin. You really can't compare the 2 items, because they both have a completely separate niche.
