Russia's 5th gen stealth fighter by Sukhoi
Air superiority and high-speed interception
The F-35 Lightning II is the world's most advanced multi-role stealth fighter with 1,000+ delivered and combat-proven in multiple conflicts. The Su-57 Felon is Russia's 5th gen answer with superior speed and maneuverability but only ~30 produced and limited stealth capability.
The F-35 wins on stealth, sensors, network warfare, and proven combat record. The Su-57 has better raw flight performance but lacks the production numbers, sensor fusion, and allied interoperability that make the F-35 dominant.

Limited (Ukraine/Syria)
In raw flight performance (speed, maneuverability), yes. In stealth, sensors, and combat-proven capability, the F-35 is significantly superior. The F-35's sensor fusion and allied network give it massive advantages in real combat.
