You guys are pretty much all missing the point.
1. The Russian fighter is obviously a stealthy deep strike aircraft. It's freaking huge (F-111 size) with large internal weapons bays. If used as a pure fighter it can probably carry double the missile loadout of an F-22, triple or quadruple what an F-35 can carry.
2. The F-22 is an air dominance fighter with no compromises, but because of stealth it can't be modded to an A/G workhorse like the F-15D became the strike eagle. Comparisons to the F-22 and this new Chinese fighter are like comparing an F-15 to an F-111.
3. The F-35 is a stealthy viper with better information integration software. Those systems can be put in ANY future aircraft and are true advances, but the plane itself is little more than a stealthy F-16. The F-35 is gonna suck at air superiority and it doesn't have the range or payload to replace the F-15E. It is also only front aspect stealthy, so anything left alive after the strike is over will take a shot at the retreating F-35s after they drop their 2 bombs and run out of gas, because they are not rear-aspect stealthy.
This Chinese fighter is something the US wishes it had the money and balls to produce, a stealthy deep strike fighter to be the true successor of the F-111, F-15E, and B-58 hustler. It would be a massive game changer as a strategic deterrent for the US against any potential adversaries, and could actually potentially save trillions of dollars since it could allow us to reduce deterrent commitments elsewhere and act as a deterrent we might actually use against any smaller high-threat country that doesn't quite deserve nuking. But we're not going to make one, even though the concept was pretty fully worked out with the "stretch" F-22 proposals.
