This is a comparison on 4th generation parameters, and absolutely misleading. Put F-15C Eagle in there, and similar claims can be made for it.
F-35A have excellent maneuverability for a single engine design by the way. Pilots are reporting that its rudder-assisted turns are incredible and deliver a constant 28 degrees of turn a second. Pilots are managing 9G+ turns while putting the aircraft through its paces. One source is reporting T/W ratio of 1.16.
"A former F-15C instructor pilot said he consistently beat his former jet in mock dogfights."
However, F-35 variants are not just about maneuverability (this was the strong point of 4th generation aircraft); it is about what its onboard systems can do for the pilot in virtually any situation. F-35 variants incorporate a powerful EO/IR 360 degree situational awareness system known as Distributed Aperture System (DAS), which facilitate its targeting mechanisms in virtually any situation [BVR or WVR].
"In the realm of air combat, a pilot flying an aircraft with DAS installed should almost always know where the enemy and friendlies are during a dogfight. The system really works as a smart optical search and tracker at longer ranges, notifying the pilot of interesting things it sees, both in the air and on the ground, and as a virtual "back-seater" born with x-ray vision during close-range combat." - Tyler Rogoway
Simply put, DAS enable F-35 variants to obtain a lock on the opposing aircraft from virtually any angle even in WVR situation, and the pilot only need to press the button afterwards.
"As a mature F-35 and an enemy fighter merge during a theoretical dogfight, DAS will keep that enemy aircraft locked up without pointing the nose of the aircraft anywhere near them, and the pilot can fire a network-enabled AIM-9X Block II advanced Sidewinder at it. DAS would transmit the enemy aircraft's telemetry to the highly maneuverable missile in-flight, which has a high probability of destroying the enemy aircraft as it bleeds energy in a hard turn. Meanwhile, the F-35 has accelerated out of the fight or pressed the fight further, taking advantage of the fact that the enemy aircraft is now on the defensive (if not destroyed), and at a low energy state." - Tyler Rogoway
In the shoes of an opposing aircraft, you might have excellent maneuverability but you are still in big trouble because an F-35 variant can simply obtain a lock at you from any angle in WVR (DAS factor), and put an AIM-9X Sidewinder up your **** afterwards.

5th generation fighter class is about VLO, avionics, sensor systems, sensor fusion and automation - domains in which F-35 variants excel. These are the domains in which SU-57 should be measured.

For fun sake; an F-35 on 7G limiter (artificially imposed) pulled this maneuver:
