Key differences:

There's a 2-seater planned for the T-50;
The T-50 has a slightly larger (78.8 sq. m. against F-22's 78.04) and better-loaded (330 kg/sq. m. against 340, max. 470 vs. 487) wing, which makes it more agile in dogfight, combined with...
3D thrust-vectoring engines (Saturn Make 117 - no official name for the engines, they're still referred by development code) - the F-22's engines are 2D-vector only;
Improved radar signature, claimed to be smaller than F-22's (0.3-0.4 sq. m. in centimetre-range radar waves vs. F-22's 0.4-0.7);
Higher thrust:weight ratio (traditional for Russian fighters) - 1.19-1.38 combat-loaded, 0.84-0.97 max. weapons+fuel load/max. weapons load (1.17 combat/0.88 max. load for F-22);
Higher internal fuel load, 12500 kg., allowing the T-50 to work as a long-range interceptor with a high supersonic dash speed;
Higher maximum airspeed - 2100-2600 Km/h depending on altitude (most planes can actually go faster than their maximum rated airspeed, but at the risk of airframe damage);
Lighter than the F-22 (yes it's larger, but it also weighs less): 18500 kg. empty (F-22's 19820);
Higher max. G-load (10-11 g against 9.5 for the F-22).

If anything the performance is bound to be improved - the numbers are given for the T-50 prototype, not the production version (compare the T-10 with any Su-27 production variant).

Overall it's pretty similar, but the T-50 is designed to be an agile dogfighter with 3D thrust vectoring, a concept the USAF has forfeit. It has fully mobile fins (whole surfaces move, there're no rudders).

It even has vocals... by Blaster Bamboozle: the Balladeer from Beta Ceti!

The Swarm

Deep inside the smelter I have found a killer swarm
Lancing homing flying box of death
The red ones are a challenge they can sneak in from behind
The blue one can make all the others stronger

All these flying death machines
Are made from what is mined here
Virally infected and then weaponized
All these flying death machines
Are made from ore refined here
They must be stopped destroy the smelter
Or they will reach earth

----------------------------------------------------------------------------------------

Deep inside the smelter we have found an obstacle
Flying lancing flaming ship that must explode
Red ones you corner him
Blue ones you amplify them
Grey ones you deal the final blow

All these flying death machines
Are made from what is mined here
Virally infected and then weaponized
All these flying death machines
Are made from ore refined here
Virally infected and then weaponized
All these flying death machines
Are made from what is MINE here
They must be stopped destroy the smelter
Or they will reach my--

-------------------------------------------------------------------------------------

Blast the flying box of doom

Dodge the homing rocket

Grab the upgrade green
++
x2

All the keys and reach the core
They can't fight me anymore
Go, blast away and start the countdown

Find the exit hatch
Kill the power patch
Head up, to the surface
I start to breathe again

An interesting little track with a 3/4 time signature and a rhythmic style somewhere between Depeche Mode and Aphex Twin.  The album tag does say a thing that might make you wonder why I'm putting this here, but this track is likely only going to play in Xfing's mission without actually being on the album itself... sorta like Broken Wings.
Anyway I wanted to see what you guys thought.

Strange spirit awaits the changing of the tides
Nothing's left but for the beast; virus, inside
...
Swishing tail tells a story
Dark underwater fantasy
Changes shape, you don't know why
Your world; under dark skies
...
Body and soul torn apart
Reach into you to devour your heart
...
Moon's rising out here but do you see?
Now you don't want to ever leave, oh no...
Strange eyes -- strange mind, new and naked form
Plunging headfirst into dark depths, dark storms

But there's something else inside
Your swishing tail tells a story
Not such a fantasy
The spirit waits, the spirit tries to hide
And there's something else inside
I am the pain, yeah
I'm the incoming void; forever...
...
Body and soul torn apart
Reach into you to devour your heart
Body and soul torn apart
Reach into you to devour your heart
...
Forever... forever... forever...
