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.
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.
