Rafale 1:1 would be determined by the best BVR capable fighter, which in our case won’t be F-16 B70, J-10C or even J-20.
Radar matters and the BVR missile and we have Block 3 which is the best suiting our needs. You can wish for Block 70, but can you get AIM-120D ? Definitely not !!!
Block 70 F-16 would be a sitting duck in front of Meteor and AIM-120C5 which we use.
Even if you talk about J-20 or J-31 or even J-10, none of them provides an EVEN mightier AAM than PL-15 at the moment, which our thunders can also use. So best bet is Block 3.
Kudos to Thunder Program Managers and Planners, how far sighted game they played and luck was with them as well. Thunder is a blessing.
If you want something even better than that, J-20 or SU-35 (with J-20 Radar and avionics and AAMs package) is the way to go.
