While I am not sure any of them are really very good, we can at least check off some stuff. I added letters before them for reference.

C is easy to eliminate because the use of him at the end is incorrect. The sentence is saying No other is as good as he is. So him is in the position of a predicate nominative and should be in the nominative form he.

D is also easy to eliminate because it does not really make sense. The friend got good? The words are just jumbled.

E is questionable in a few ways. For one thing if the person never had a friend as good as the person he is talking about, then I guess the person was not his friend. That's a weird change in meaning.

All of them share the error of using the form have got. For one thing, the correct or standard form is have gotten. Having said that, even if have gotten were used, it would not work anyway, because the sentences are not about getting friends, but about having friends. So the got, or gotten, is unnecessary and its use nonsensical.

If I had to choose one, I would choose A. If the word got were removed, A would be a decent concise sentence.
