Dude,the chinese made planes have never been put to test in a real combat situation anywhere in the world,barring vietnam.Wherea F-16 or Sukhoi's have been used in war situations.
I had my doughs but now you just proved what an idiot you are!
71 war?? mig-19-> F-6! by far one of the most lethal fighter in the subcontinent and even shoot down much more superior IAF mig-21s!
Neither Su-30 MKI, or Mirage-2000 have got into any battles so that does not mean they are not tested and they suck ohh in fact none of Su-30 series that China and IAF operate have seen any combat...
