Will anyone tell me if the following sentences are correct.

1. I have never read such an interesting book as this.

2. I have never read such an interesting book like this.

3. I have never read an interesting book like this.

4. I have never read an interesting book as this.


I want all the sentences sound the same.
Are "like" and "as" the same?
I am not sure if "such" is needed for 3 and 4.
