Canards are inferior to tailed aircraft in stealth terms, think of it this way:Do you think, at this angle, placing the canards behind the main wings will reduce rcs?
Welcome to SDF, 60% China fanboys / Chinats, 30% China bashers, 10% moderates.Actually the stealth penalty of a canard design is significantly. Not just we have a completely visible control surface frontally the gap between airframe and canard is a trap for radar waves.
Something things can be compensated with the right flight control system and efficient RAM coating. But nothing will fully compensate for a visible control surface frontally. Even ignoring that the J-20 is quite the bastard design which also deploys all moving fins and deep central strakes.
I think it's not a good showcase of discussing in good faith if people accuse other people of being fanboys or bashers or anything. It's mostly tiresome.
Also talking about stealth. It doesn't take a lot to realize the more visible movable control surfaces are from the frontal arc (including undesirable elements like the gap between airframe and canards) the potential worse is the RCS.
Delta-Canards designs (there are more than enough such planes in service) have very interesting and impressive aerodynamic performance characteristics. But the stealth implications basically killed it for any American, Russian and European future concepts.
