Russia based the Su-35 on the rock-solid Su-27 platform, so its status as a "supermaneuverable" fighter is a matter of fact.

Russian pilots familiar with previous generations of the Sukhoi jet family's thrust-vectoring capabilities have carried out spectacular feats of acrobatic flight, like the "Pugachev's Cobra."

On the other hand, the F-22 has a great thrust-to-weight ratio and dynamic nozzles on the turbofan engines. These mobile nozzles provide the F-22 with thrust-vectoring of its own, but they had to maintain a low profile when designing them to retain the F-22's stealth edge.

Possibly, the Su-35 could out-maneuver the F-22 in a classic dogfight.
