You have inferior S300 and PATRIOT which failed to stop Kamikaze Drones and Cruise missiles attacking Saudi oil sites
PATRIOT is inferior to compare with S400 to hit Fighter Jets , Bombers and AWACS
S400 has the longest kill record in the world
( S400 shot down Ukranian SU-27 over Kiev from Belarus 150+ km away )
Thanks to 380 km 40N6 and 250 km 48N6 Missile with speed of mach 5,9
S400 is not against low-flying cruise missiles and Kamikaze Drones
Russia needs modern and layered Air Defense Capability
On the other hand
Turkish KORKUT , GURZ and HISAR will protect S400s from low-flying cruise missiles and Kamikaze Drones
The Patriot system that was deployed near Abqaiq oil refinery in Saudi Arabia was equipped with a single radar system having 120 degree FOV - this radar system was facing Yemen. Iran exploited this loophole to attack Abqaiq oil refinery in 2019.
Russian S-300 and S-400 systems are equipped with several radar systems that collectively provide 360 degree FOV. Russia, US and Israel had an understanding on the issue of not toppling Assad regime.
But there were situations in which US felt the need to attack infrastructure of Assad regime,
and Israel was more likely to engage Assad regime due to its focus on attacking Iranian supplies to Hezbollah and Assad regime.
Both US and Israel came up a strategy to neuter Russian S-300 and S-400 systems with advanced applications of Electronic Warfare (EW) and stealth without resorting to destroy them while attacking infrastructure of Assad regime.
Russian S-300 and S-400 systems are particularly exposed in the ongoing Ukraine - Russia war wherein both sides are hesitant to attack opposing forces. Russia has lost several S-400 systems in the war. Ukraine has also lost a number of its S-300 systems to Russian forces in the war.
Ukraine has destroyed more than five batteries of Almaz-Antey manufactured S-400 surface-to-air missiles in Donetsk Oblast, Kherson Oblast, Tokmak and Crimean peninsula using cheap kamikaze drones …

Patriot systems given to Ukraine might be more advanced than Saudi variants. These systems are deployed around Kyiv and
have 100% intercept rate - this is truly remarkable.
Patriot systems given to Ukraine have shot down Russian cruise missiles, Russian helicopters, Iskander-M quasi-ballistic missiles,
Kinzhal hypersonic missiles,
advanced Russian jets such as S-34 and S-35, and different types of drones including elusive Shahed-136/Geran-2.
These Russian munitions are advanced, accurate, and very dangerous. Few systems in the world can neutralize these threats, particularly in a swarm format.
Just one gets through, there goes a costly launcher...
The bottom line is that Patriot >>>>> S-400 and S-300 systems when configured for excellence.
