"Best" has to be defined against a standard...you saw how tough it was to define the standard in the first post.
Personally, I like all aspects, so I won't be best at anything, but will be well rounded. It's good for squad ops.
I love the furball - I have decent SA and that pays there. One v One, I am never very good (DA environment).
I don't fear anyone, but I would avoid Greebo in an F6F if I wanted to "live".
