I wonder sometimes when some members claim... chinese jets are far advanced and generation ahead of Russian jets... Ironically they got lot Su-30's and and the jets copied from Russian su-27's... yet they claim J-11D avionics, weapons, Radar packages are generation ahead of Su-35.... just because chinese copied su-27 named as J-11A,B.D... Do they checked How many Su-27 variants are available and what are the major difference between Recent versions.... may be J-11D got goodies than J-11A... but claiming generation leap over the most advance 4++ jets is just silly assumption...
