Indeed, but the Russians claim that they are stealthy, after all, even the Su-37 has a significantly reduced radar signature. I guess we should give them the benefit of the doubt. If we don't consider these a/c, what are we left with? The F-22 and the F-35? If the S-37 still has some hope of one day leading to an operational fighter jet, the MiG 1.44 is deffinetely not going anywhere, as the Russian AF does not want to have anything to do with the a/c.

Any flat surface decreases the stealth signature of an aircraft.
Canards therefore do increase the RADAR crosssection, unless they replace traditional elevators. But that would most likely necessitate a larger wing which is also bad.
If you check the S-37 it has a very sharp and straight leading edges. Compare that to the far more blended design in the F-22 which was used precisely to reduce radar cross section. It does have RO (reduced observability) features like the small rounded air intakes which remind of the F/A-18 and an ogival instead of round nose (but the Soviet have been using that shape for at least 40 years so it's not new).
