I meant numerically.
Heck, I'm sure that the best 4th gen fighter is Su-35
But keep in mind that NATO's F-15s are nearly as good and much more numerous.
And those are just the fighters, there're also AWACSs, tankers, recon, comm planes, all of which contribute to battle effectiveness as much as fighting systems themselves.
Actually in comparison with all US 4generatin fighters ,Not only the Su-35 is superior but also all thousands of SU-27s and MIg-29 with upgraded avionics that Russia have.. because they can see first and attack first.. and in the case of the Sukhois they have thrust vectoring engines.. means that no F-15-f-16-f18 stance a chance in visual combat against any Sukhoi.. this was even confirmed by an American pilot of an F-22 ,who saw how India wiped
all their 4gen planes in RED FLAG exercises in 2008.. So he told that is was scary how Russia technology dominate their 4th generation planes. in a dogfight you cannot win a sukhoi super maneuverable using linear thrust engines.. pilot skills being the same.

When it comes to F-22 raptor and F-35.. Their numbers are not good enough to make a difference , major problem the raptor will face is that it will be detected as soon launch a missile and the the SU-35 can jam the raptor missiles with its very advanced ECM capabilities. SO the raptor will see first ,first first but will not score a hit ,and once the SU-35 short the distance is game over for the raptor.. since lose a lot of energy when doing tight turns ,major weakness confirmed by Rafale and Eurofighters pilots who already defeated it. SU-35 in the other hand is a True vector engine fighter , not only 1 Y axis dimension but in X dimension too. With its infrared passive sensors (that the raptor dont have) the Su-35 can see the raptor easily at up to ~50km-80km according to Sukhoi claims. That is very decent medium ranges of interception.
US strong point vs Russia is in the navy vs navy in open sea when using their aircraft carriers + combat jets(away of Russian territory).. and also strong in intercepting ICBM with their navy ,also geographics/political advantage in first strike capability,can use any territory in Europe to attack Russia.. Russia cannot use Mexico or canada to attack US.The US navy can overwhelm any navy in the world including Russia for sure albeit not without suffering massive losses.. But its army is mediocre at best ,specially its missiles forces.
In a conventional only war ,Lets say US choose to invade Ukraine with its army and tanks with Russia threatening to fight them if they do it. And US deploy all their impressive number of massive Airforces Poland and Romania..
The major problem they will face is that Russia Kaliber missiles have 3,600km range and can hit any part of Europe ,and any airforce military base. So Russia can do direct hits on their military bases anyplace in europe and just using their land missiles forces the most powerful in the world...

NATO will need to move their airfoces not only away of Russia combat range but away of their combat range too. It means that in a war between USA and RUssia their airforces will play no role at all. because will be at range of Russian cruise missiles or at range of S-400s. It means the NATO will no longer be able to count with air support in a war against Russia. And then when NATO armies gets closer ,Russia will start firing iskanders with 500km range and 5m precision. This means Russia can do Direct hits on the supply lines of NATO in their operation bases..
Russia also have a huge advantage on Sam Defenses and mobile sam defenses ,not a single American slow tomawahk missile will bypass a zone protected with highly mobile Pantsirs ,Tors and Buks. In the other hand US and Allies will have a pain dealing with Supersonic mach 3 missiles hugging terrain and coming from all directions *at the same time*.
Russia army is very dynamic can move every thing with their foot soldiers to any place ,that is sams ,electronic jammers and offensive weapons to any part the army move, NATO army is very static and purely offensive.they depend on airforces for their defenses 100%.
Simply NATO is not prepared to fight Russia in a conventional war (specifically in the case they fight near Russia) main land. All western tanks will be useless if Russia can knockdown them from 90km away with Smerch drone+lazer guided rockets. This is why NATO tactics is 100% based in weakening RUssian economy. To give them another Afganistan. That is a proxy war.. NATO instigate revolutions and arm radicals with weapons in nations important for Russian interest. Weapons clients like Syria ,Iran or major trade partners like Ukraine,this way they can avoid a direct war with Russia that they can't win. US can be more effective with sabotages to Russian economy and Sanctions. This is the Reason Syria but also Ukraine is attacked.. they want to use Syria discovered Gas fields to supply Europe and cripple Russia economy. They also after Ukraine because Russia pipelines pass through Ukraine and large part of Russia economy depends of their business with them.
here is a comparison of US vs Russia airforces.. and why in a fight vs Russia or China they will NOT have air superiority..
