天才与蠢才， 只差一个字。

How would you translate the above?

1. The genius and the fool, a word of difference.

The first phrase is probably closer to 天才与傻瓜.

2. Brain vs brawn, a letter makes the difference.

3. The brainy and brainless, only the end differ.

The third one is my favourite translation, there is a subtle pun on the word “end”, the last syllables are different for both words and the work done by the brainy and the brainless generate very different end results as well.
