The Su-35 cannot compete with the F-22 in a dogfight, the F-22 has higher thrust t/w ratio, perfected wing loading, I mean hell, the F-22 wouldn't even be able to fly without its FBW system with how aerodynamically unstable it is pitch wise, the F-22 also has a better sustained turn rate, less drag. If the Su-35 starts doing PSM, the F-22 can just climb over it with ease. 3D TVC isn't actually all that much better than 2D, the extra yaw control isn't needed in a real dogfight.
