What is the difference between くらい～はない & ほど～はない?


  * リーさん **ぐらい** 動物好きな人はいない。
  * リーさん **ほど** 動物好きな人はいない。

What is the difference between these two sentences.




In this specific case, the two sentences are interchangeable and there is
almost no difference in meaning.

But that does not mean くらい/ぐらい/ほど are always interchangeable. For more generic
discussion, see the following questions:
