Hello, Tommaso:

This is how I understand it:

  1. Both are “correct.”

  2. “as … as” is probably the more frequently used.

  3. Some people prefer “so … as” in negative sentences.

Why? Well, here is one explanation:

English speakers are so accustomed to “as … as” in affirmative (positive) sentences (for example: Is your country as large as the United States?) that some speakers feel a negative sentence gets more attention if you use “so … as” (for example: My country is not so strong as yours).

HAVE A NICE DAY!
