The article never really compares the MiG-31 with the F-16 - it has almost nothing to say about the missiles and electronics of the latter.
It reminds me of a time I went to a Honda dealer and started listing the reasons why Toyotas had better engineering.
The salesman appeared to take it very personally, but I was thinking "duh, can't you see I want a Honda because I know all about their competition and yet I'm here?". Maybe he thought I worked for Toyota.
