It's Su-47 Berkut, and that plane hasn't even been deployed for combat yet, so there's no way to tell.
The Lightning II isn't an air superiority fighter so it probably doesn't belong on this list either.
The Berkut is highly maneuverable, and has about the same avionics and weapons as the Raptor, but the defining difference is the pilot, and the side so to speak. The Raptor will be piloted by Americans, who are traditionally superb fighter pilots. American doctrine is flexible, allowing the pilot to choose the best course at hand. The Berkut will be piloted by a Russian. He/she will be much more rigid, and while Russia has had good pilots before, they are far less flexible then his/her American counterpart. The Russian doctrine, like so much else, depends on the CO or NCO to take charge, and direct the other fighters (I'm pretty sure, but I was unable to find a citation for that). As such, in a one-on-one dogfight, both planes would match each other, with the Raptor being maybe a smidge more maneuverable (due to the computer controls), but the pilot flying styles would make the difference.

They could, but why would they waste the money? we have learned better, and no longer make them. the Military Machine likes to dream up more expensive toys. then to create neat little wars to use them in. while people starve in the streets at home. Nice move there for sure.
That's because we'd prefer to spend money rather than men.
Honestly, there hasn't been real air to air combat with real combatants in 30+ years. We don't really know what the key to success is. Granted, the f-22 dominates in stealth, maneuverability and avionics so it will be excellent regardless. The main problem is that it comes at incredible cost. The best fighter of the future may be a relatively cheap airframe that is basically just a bus for long range missiles and electronics. Or maybe stealth works well enough to limit engagement ranges to dog fights so that you can dump the LPI radar and carry a lot more cannon ammo.
Actually the Eurofighter dominates in manouverability.
Yet F-22 is clearly the best overall fighter plane.
