what is the difference between Su-35S and J-11B?

inspired by Deino’s post..

major change of Su-35S from Su-27 is:
new PESA radar
new engine 117S with thrust vectoring
removal of air brake
more use of titanium in structure, longer life
new cockpit

major change of J-11B from Su-27 is:
new mechanical steered array radar
new cockpit with 5 mfds
new MAWS
supposedly WS-10 engines, but Huitong site says quality sucked so still using the same Russian ones.

anything else? how about J-15?
