It does all the flankers made by China are equivalent to the Su-33/Su-30MKK performance wise with avionics and weapons similar to F-15s such as the F-15E or F-15k at best.
The Su-35 is closer to the Eurofighter and Rafale in aerodynamic performance and avionics in the league of the first Rafale versions
Unless you have access to the blueprints of every single subsystem aboard Chinese Flankers as well as those of Su-33/MKK or F-15E/K, by no means are you qualified to judge the capabilities of these respective jets.
The J-15, J-16, and J-11D feature AESA radars, upgraded cockpits, integrated avionics, upgunned 140 kN engines, next-generation EW/ECM suites, increased use of RAM and composites, and much more, most of which may or may not even be found aboard the likes of the Su-35/Rafale/Eurofighter.
