Considering the fact the convential airframe F-22 is not very good at air-combat comparing with the ground-breaking unique airframe of J-20 (lifting-body co-plane canards blending with leading edges), when a F-22 is facing a J-20, the result may not much different than trying to pitting a SU-27 against a J-10.

Lol, it seems that you are still quite bitter about the obvious facts I mentioned about PAK-FA and Su-27, anyway, this is a very happy time for me so I dont want to waste anymore of my time on little issues like how J-20 will pwn PAK-FA etc.
So you can feel free to go ahead to brag how advanced the Su-27 nicknamed PAK-FA is and will be, I wont bother you here, OK? hehehe.
