If you are J-10 fan boy, you would like to hear all good about it, which I'm not, so I'm free to compare J-10 with even Mirage or Gripen.
If that makes sense to you or not. I can't help.
Why i compare the air-intake of F-16 because, J-10 design has tons of inspiration from F-16 and it's design history.
I'm questioning the bottom air intake integration on J-10 in general, which they tried to revamp in transition from A-C. Basic ide was to compensate the basic design error and wrap it in DSI upgrade. They did the whole nose job BTW.
Still it looks which gives impression, that canopy+nose structure of another design has been welded on a fuselage of J-10.
It may be my individual observation, which you are welcome to argue.
For better understanding, just look at F-16 air intake. It looks like an integrated design, unlike J-10A &C below, which looks, more like a patch job.
It may still be a great fighter, thanks to the FWB but i can give only 6/10 to it's structural design.
