NAA President and CEO David Ivey said the fighter’s performance has “established the unquestionable superiority of the Raptor, a culmination of years of visionary design, rigorous testing, and innovative manufacturing.”
The F-22 was specifically cited for its performance in the 2006 Northern Edge military exercise. During this large-scale, force-on-force exercise, Raptor pilots flew an amazing 97 percent of their scheduled missions, achieved an 80-to-1 kill ratio against their Red Air opponents, scored direct hits with 100 percent of their satellite guided 1,000-pound GBU-32 Joint Direct Attack Munition air-to-ground weapons, and increased overall situational awareness for the entire Blue Force through the F-22’s integrated avionics.

Various maiden flight and delivery deadlines have been mentioned. The fighter is expected to make its appearance sometime between 2008 and 2010. In late 2008, Colonel General Alexandr Zelin, commander of the Air Force, said the warplane would perform its initial flight in August 2009.
Last summer, the fighter's design was approved, and the prototype blueprints were delivered to the Komsomolsk-on-Amur Aviation Production Association (KNAAPO), where production will reportedly be sited. Currently, the company is building three experimental fighters for testing.
These prototypes are due to last for five or six years. However, a production run will not be launched before 2015.
Although T-50 specifications remain classified, fragmentary data on its engines imply that this heavy-duty fighter will have a take-off weight of more than 30 metric tons and will be close in dimension to the Su-27.
The Tikhomirov Instrument Engineering Research Institute, which designed the Irbis radar system for the Su-35BM Flanker generation four-plus fighter, is now developing the T-50 warplane's radar. It appears that its radar and fire control system will be based on the Su-35BM system.

As to the original question the Russian aircraft appears to be an upgraded SU-35 with stealth features and using the same engines as the SU-35 and thrust vectoring. However to say or imply that it is a competetor to the F-22 is way to premature. The F-22 will for sometime to come have the stop spot as the only 5th generation fighter. I did not say the best fighter in the air because that reputation assumes combat performance one in which the F-15 Eagle at the moment sits on top of.
