Eurocanards vs J-20 and J-10B

Continuing from another thread and separating it as its a different topic than what the original thread intended for

Some people argued here before that the Eurocanards stand a great chance if ever they face an F 35 in combat.

Now to change the topic slightly, how do you think both or either would fare against a Chinese J-20 and J-10B, which according to many might be sacrificing maneuverability for speed and weapons load.

Might help change the discussion away from the Rafale vs Typhoon trend.
