There are so many wrong things in your post.
Listen man, su57 is not as good as f35, I would say not as as good as j20.
But it's better than rafale in stealth, and not inferior in terms of avionics even by a little but.
And those exposed engine, are for protypes, production varient is fully covered one.
Aa for spectra, it's a good suite but not some best in world suite, again it's a very good suite, but highly overhyped, many modern suites can rival it.
As for the Russian missile.
It's not just the missiles fault.
Bars radar of su30mki is easier to jam,also has significant clutter.
And pak had ew plane in the area.
And the radar and missile both are old.
Even latest Russian missiles are little bit behind, china.
But little bit only.
As for the radar of su57.
It's an GaAs aesa radar called no36 belka
Its based on su 35's irbis E radar which itself is lot better than su30mki'a no11 Bars radar.
It's the first aesa radar for fighter jets by russia so unproven, but they have experience in aesa tech in other areas, for example russia has developed and in service, early warning, long range surveillance and fire control Aesa radars for ground air defense
And su30mki is not shit that we need to upgrade it, in the last 25+ years avionics tech have evolved too fast.
It's the stupidity to churning out same standard su30 for 20 years.
Even russia moved on to su35 in mid 2010's.
eurofighters are also getting upgraded, as uk and germany made somewhat similar mistake as us, france on the other hand did the right thing, they rafale f1, rafale f2, rafale f3, now rafale f4 and in future rafale f5.
and unlike other countries where block have some advancement, in case of france these blocks had " significantly major upgrades"
Though su57 if we dif the same thing we did for su30mki, then by 2035 su57 will start getting outdated as both f35, j20 are getting continous upgrades.
russia also plans to go this continous upgrade route, that's why are not make a large single order for su57.
So far 76 orders for single seat 57 are given, while work on twin seat su57 has began Russia plans for 200+ by 2035-40.
For su57 The Mission computer is digital, the screen layout makes the cockpit look old.
And the layout is pretty old school looking, but all those screens are lcd, just not arranged together in wide signal display.
And as for the fit and finish, your probably talking about the prototypes again.
Eots= irst(flir) + Laser targeting pod in crystal dome.
Su57 doesn't have crystal dome and laser targeting pod, now crystal dome further help in some more rcs reduction
But for laser targeting there are some people who do question whether laser pods are still useful especially in future with the coming of gps/ins, EO, IR guidance.
Also su57 has side facing aesa radars array, and back facing too, the only one to have these.
It is also the only fighter to have DIRCM right now.
Now f35 will sure smoke su57, even j20 has better chances.
But f22, na.
It's a 30 year old plane that's overhyped.
It's the least capable 5th gen.
Su57 is second least capable one.
Infact the only thing "5th" gen in f22 are stealth and engines.
F22 lacks any irst/eots system.
Su57's irst, with good environmental factor will detect f22 first and track it first.
So russia did "succeeded" in making The raptor killer, though now it has to face f35 lightning2.
Plus f22 uses lot of metal in its construction
By structural weight f22 has about 37% composites, tejas has 50%, f35 has 65%.
Lot more metal, higher ir signature.
That's the reason f22 is undergoing "upgrades" to f35 standard, but avionics upgrades can't provide it the same stealth( yes unlike the propaganda, f22 is less stealthy than f35 from front, f35 is the most stealthy 5th gen fighter jet.) and reduced ir signature as f35, That's the reason usaf is testing those shiny coatings on f22, in an attempt to try to reduce it's ir signature significantly, so it can take on j20 and su57.
If this testing doesn't get any results then most likely f22 with go in retirement home, replace by f35 if usaf wants same stealth role, or f15 ex.
There's a reason there were talks about retiring f22 by 2030's.
For more detail here.
Today many nations including us have developed own versions of things like RAM, RAS but unable to reach lowest RCS of F-22
That seems pretty exaggerated, due to propaganda in support of f22.
That marble size rcs of f22, at 0.0001-0.0002m2 that us military talked about, is just wrong, its 100% just from one angle, the most optimised angle, viweing angles of jets from front cover 120°+angle, that's why median or avg rcs is better.
The same here for f35's golf ball size, though its more accurate than f22,
Based on simulations of shape( assume all surfaces to be metal), "average"...
