There is no good source of performance information for either plane. One is classified, and the other is classified and under development.

My guess is that the F-22 will have the edge in stealth and high speed flight, while the final PAK-FA might have better low speed performance.

Actually, I think the PAK-FA only has two "advantages" over the F-22;
1) The EO/IRST system
2) The pricetag Very Happy

Any real advantage would come from sensor fusion and advanced avionics, rather than aerodynamic flight performance. It is possible that the PAK-FA might have a higher top speed, but that doesn't count for much if the engines expire at the end of the flight.

Here's the deal: The USA, via the F-22, has ramped up the game of air dominance. In order for the opposition to counter the -22 "threat" they were forced into developing their own 5th gen super fighter. In doing so, we have done a very intelligent move in this chess game. We're never going to have a shooting war with either Russia or China. But world politics being what they are, we're likely to have shooting conflicts with their client states such as NK, Iran, and others. Those client states can't afford to purchase these 5th gen fighters. What they're left with is older and less capable 4th gen aircraft, and not in large quantities either. So then, guess what the US did: we developed an aircraft called the F-35 that is cheaper than the -22, will be bought in large quantities (even as the program will invariably be cut to some degree) that is more than a match for 4th gen fighters. I'd wager my money on a single F-35 versus 4 Flankers or Fulcrums each and every time. When Russia is done developing the Pak Fa, maybe it will be faster than -35, and maybe it will carry more AAMs internally, and maybe it will be more maneuvable than the -35 is certain regions, but it is irrelevent because the nation states we're like to have future conflicts with simply, plain and sinply cannot afford to purchase that aircraft. Hell, even Russia itself is only able to afford (projected to be able to afford) about 270 of that aircraft. Along with the US strategy of exporting the -35 to other nations around the globe, they'll hardly be any place in world that matters where there won't be at least a squadron of -35s to worry about. Can't say that about the Pak Fa. Air dominace is more than simply fighter stats vs fighter stats. Just my $0.02.

That sounds familiar. Kind of like a mash-up of Reagan's build up and the Winchester handgun proliferation.

Aren't you forgetting something here.
India will also be the lucky owner of Pak-Fa/FGFA jets.
It is only fair to say the Pak-Fa/T-50/FGFA jets will reach a higher number than the F-22.
But i agree, it is still too early, we have to wait and see what the price will be and how many will be produced/exported.

The PakFa has an IRST (Infrared Search and Track) and "might" have some type of EODAS functionality.

That is the big unknown. The Sukhoi Su-30MKI OLS-30/OLS-35 system is no match for the EODAS in the F-35.

The OLS-35 is good out to 20 miles front-quadrant targets & 60 miles rear quadrant. This will not beat the F-35s radar range, and will not beat the F-35 EODAS effective range. The OLS includes optical zoom, so it has to know where to look. EODAS is a wide angle system.

It is not just raw sensor capability that makes a platform, its the signal processing behind the sensors, and how its presented to the pilot (sensor fusion).

I'm splitting hair, but the OLS on T-50 is called OLS-50. It is slightly different from any Flanker OLS-30.
There is one positioned on the tail, another one right behind the cockpit, and then its the larger IRIST in front of the cockpit.
Not sure if it will have the same two underneath airduct sensors like seen on Flankers.

Sorry I was not clear. I was not trying to confuse the Pak Fa IRST and its separate MAW systtem:

Pak Fa IRST = F-35's EOTS
Pak Fa MAW = F-35's EODAS

Apparently, they've managed to fix the structural problems that plagued PAK-FA #1.

PAK-FA T50 is rumored to use stealth panel layers reverse-engineered from F-117 generation 1 stealth panel (shot down in Serbia). Even if they managed to duplicate it 100%, it's like T-95 Black Eagle tank using Chobham 3rd generation vs Challenger 2 using 5th gen Chobham armor. Whether the PAK-FA T-50 has stealth capability remains a question mark. Could be just low RCS as earlier US stealth could not get it works on pure fighter with afterburner jet engine which is also the main reason why F-117 lost its F-19 designation as it is not qualified to be fighter but instead an attack aircraft.

Quite possibly they have, but the tests described in the link do not require high g maneuvering. Until we know what the maneuver limits are, we don't really know if the problems have been solved or not.

From the linked article :
...The first prototype, T-50-1, is undertaking preparation for a flight test program involving flight at super-critical angles of attack and super-maneuverability...

Presumably this aspect of testing will stress,the aircraft significantly . Any significant differences in the way the Russians approach development and testing vs. the West?

Absolutely wrong...it was NEVER designated F-19.
