This is simply not true. For one thing, the Rafael's AESA radar is superior to the Su-35s Ibris-E PESA. All Russian fighters, including the Su-57, lack sufficient BVR capabilities. The Su-35 can definitely outperform the Rafael in WVR with its fancy thrust vectoring but that is about it.
Airborne IRBIS Radar
While lacking an APAR, the Su-35 radar system can detect targets at distances up to 400 kilometers, as well as tracking up to aerial targets and engage up to eight of these targets simultaneously.
Sukhkoi Su-35S has owes these capabilities to its new Irbis phased-array radar control system. The system was developed by Tikhomirov Instrument Engineering Research Institute, a KRET subsidiary, and is being manufactured by the Ryazan State Instrument Factory, another subsidiary of KRET.
The state-of-the-art system enables Sukhoi Su-35S to detect quickly and track simultaneously up to four ground targets or up to 30 airborne targets, as well as engaging up to eight airborne targets at the same time. Besides, the radar control system has the friend-or-foe identification capability for aerial and maritime objects, is capable of identifying the class and type of airborne targets and take aerial photos of the ground.
The system can be used in any weather at any time of the day, and remain effective in the face of interference, either natural or organized by the enemy electronic warfare systems.
An oscillator with peak power output of 20 kW used in the passive phased array radar makes Irbis the most powerful radar control system in the world.
This puts the Sukhoi Su-35S radar system on par with the best state-of-the-art international designs, and ahead for most US and European active and passive phased array radars.

Irbis-E (Snow Leopard)
Irbis-E development started in 2004 and the first radar prototype entered flight tests on board an Su-30M2 aircraft acting as a test bed in early 2007. The resulting radar system provides air-to-air, air-to-sea and air-to-ground (ground mapping,
Doppler beam sharpening and
Synthetic Aperture Radar modes) modes with improved performance in intense
clutter (radar) environments compared to its predecessor, the Bars system.
In addition, Irbis has been designed to detect low and super-low observable/stealth airborne threats.
