In my opinion, the J-10 is the best aircraft in China's military industrial history, it's much more important than the J-20. Versatile, cheap, easy to maintain, high combat performance, this is a great aircraft. There are many who think that J-20 is better than J-10 because of its invisibility, but don't forget the F-117 lesson. J-20 and J-10 are like Tiger with T-34. It would be even better, if China developed a special version of the J-10, similar to the F-35B role, operating on aircraft carriers.
