Both are correct.

Answer 2

They are both correct.

Answer 3

They both are, but the first one sounds awkward. The second is more compound and smooth. 

Answer 4

The grammar is fine. If you mean punctuation, both are correct. You use a comma before coordinate conjunctions, such as "but".  This is a little informal for a formal academic paper, but would work as a review.
