Personally, I don't think he's bashing the MiG at all. He's just stating the obvious; the MiG carries less fuel that the Eagle. That can't be argued. He offers a pretty fair comparison IMHO.
As for which plane gets you more a2a kills; generally, people are more comfortable with one of the two aircraft. Some people (like myself) enjoy the Eagle, and do well in it, but others dominate in the Fulcrum. It's a matter of opinion and which jet you have more experience with. Really nothing to explain.
The subject is hit on frequently. If memory serves, there are some pretty cool graphs similar to the one in the second post in some other threads.
