J-10B/C AESA radar is definitely better than most of Rafael or Eurofightrer (which will haver AESA radar later on).
Rafale has RBE2 PESA , and some of the existing aircraft will be upraded to RBE2-AA AESA . RBE2-AA is one of the smallest AESA radars with something like 800 T/R modules ( I didn't count , pic is below so you are welcomed to try ) . Therefore, it is quite possible for J-10 B or C to have better radar then Rafale, if and when they deploy AESA .
As for Typhoon and its CAPTOR-E, it supposed to be very advanced AESA radar but also very expensive. I sincerely doubt there will be much of them deployed on actual aircraft in next 5 years.
