Now i wasn't completely satisfied by the answers given in the indian section so i decided that we should discuss it here since it concerns both india and pakistan
FC-20 vs MMRCA (Rafale or Typhoon)
Radar:-
Mr.Prins says the most key features of the super viper features when it comes to the jet capability
-AESA radar
Now according to wikipedia
Typhoon has the
Euroradar CAPTOR which although does have an AESA varient at present but is not used in the typhoon but is intended to replace Captor in the future.
mean while the rafale has the
RBE2(PESA)
So the question now being will the Indian MMRCA jet (euorofighter or rafale) feature an AESA ???
According to Mr.Prins the difference b/w the super viper and other MMRCA aircrafts was the AESA..
FC-20 on the other hand will have an AESA as the redesigned jet has a longer nose cone

Maneuverability:-
Now currently Rafale neither the typhoon does have TVC (according to my info so plz correct if the fact is otherwise)
FC-20 is rumored to have a new engine with TVC
Stealth:-
Now lets compare stealth capabilities
the rafale uses extensive composite materials and serrated patterns on the trailing edges of the wings and canards to help reduce the radar cross section (RCS)
The euorotyphoon although not designated a stealth fighter, measures were taken to reduce the Typhoon's radar cross section (RCS), especially from the frontal aspect. An example of these measures is that the Typhoon has jet inlets that conceal the front of the jet engine (a strong radar target) from radar. Many important potential radar targets, such as the wing, canard and fin leading edges, are highly swept, so will reflect radar energy well away from the front sector. Some external weapons are mounted semi-recessed into the aircraft, partially shielding these missiles from incoming radar waves. In addition radar absorbent materials (RAM) developed primarily by EADS/DASA coat many of the most significant reflectors, e.g. the wing leading edges, the intake edges and interior, the rudder surrounds, strakes, etc. The Typhoon does not use internal storage of weapons. External mounting points are used instead, which increases its radar cross section but allows for more and larger stores.
But FC-20 has DSI intakes which are more stealthy,extensive use of composites and ram so it should be safe to say that J-10 B is the most stealthiest amongst the three...
This is just a lame attempt to put the thread in the direction of FC-20 in terms of how effective will it be when going up against one of the MMRCA aircrafts which according to this vid are typhoon or rafale
