I know that the construction "It is not so much funny as interesting" is valid if I want to talk about something that is both funny and interesting, but with an element of comparison.
Is it still correct if I add "it is", as in, "It is not so much funny as it is interesting"?
Is it possible to rephrase this sentence using "less"? For example, "It is less funny than [it is?] interesting"?
If the bullet point above is correct, then would I need to use "more funny" or "funnier" if I were to turn the sentence around? I know that the correct comparative is "funnier", but it sounds unnatural to me in this sentence. But this point is irrelevant if the entire construction is wrong.
Example for the last point: "It is more funny/funnier than [it is?] interesting"
