well lets compare
the F-22 is a real fighter, that has actually been built already is in operational squadrons
The Pak FA is a mythical fighter, that only exist in the minds of the russian defense department
now which would you rather have, a real fighter, or a paper fighter ?
2. you have see a mock up of what the pak FA might look like, built on a mig 25 airframe
but they have not designed engines for it yet, nor have they developed the surface coatings
they have done no test flights to work the bugs that always crop up, out of the program yet
your looking at at least 7 years before the first prototype will fly and another 5 years before there is an operational aircraft
3. all the stats you see, are just figments of someones imagination -- since no engines have been designed, how can they know those stats ?
4. now to answer your questions about those mythical stats
the F-22 is a stealth fighter, it doesn't need to be fast, it doesn't need a super high thrust to weight ratio ( since it will never fly supersonic )
The whole purpose of the F-22 is to use AWACS aircraft sensor data or data from other aircraft
and to enter the battle space unnoticed, aquire and fire on enemy aircraft before the enemy aircraft even know the F-22's are within 100 miles of them
