tall

Dear teachers.

If (1) and (2) have the same meaning,
I wonder if there are certain situations where one is better.

(1), I like a tall man.
(2), I like a man who is tall.

Thank you in advance.

[Mister Micawber]

These sentences mean the same. It would be better to use form (1) than form (2) in more complex sentences, especially when other adjectives or adverbials are involved:

I like the tall man who is sitting in the corner.
The tall man at the desk is my boss.
