Q:

Do metaphors make the best answers? 

My style of answering questions has always about clear, easy-to-understand explanations that describe the problem and solution in detail without relying primarily on metaphors.  However, the community seems to strongly prefer metaphoric answers, as illustrated in these questions. 
Why does the community seem to prefer such answers?  Are metaphors generally better than straight explanations? 

A:

One day a young dragon came to the monastery of Master Ji-Li and said: “I am greatly puzzled, for I see that some prefer metaphoric answers, yet surely clear, easy-to-understand answers are better.  Master, tell me: do metaphors make the best answers”?  The Master kept silent, but pointed to the tree in the middle of the garden. 
“I see”, thought the young dragon. “ By pointing to a tree which had nothing to do with what I asked, the Master is telling me that Enlightenment only comes to those who abstract themselves from the world and are intimate with the infinite world of metaphors.” 
On another day, a different young dragon came to the monastery of Master Ji-Li and said: “I am greatly puzzled, for I see that some prefer metaphoric answers, yet surely clear, easy-to-understand answers are better.  Master, tell me: do metaphors make the best answers”?  The Master kept silent, but pointed to the tree in the middle of the garden. 
“I see”, thought the young dragon. “ By pointing to a tree which is firmly rooted in the earth, the Master is telling me that Enlightenment only comes to those who firmly root themselves in reality and eschew the unsubstantial world of metaphors. 
Which dragon was Enlightened?
