From wikipedia:
Although there is no reliable information about the PAK FA's specifications yet, it is known from interviews with people in the Russian Air Force that it will be stealthy, have the ability to supercruise, be outfitted with the next generation of air-to-air, air-to-surface, and air-to-ship missiles, and incorporate an AESA radar. The PAK FA will use on its first flights 2 Saturn 117S engines (about 14.5 ton thrust each). The 117S is an advanced version of the AL-31F, but built with the experience gained in the AL-41F program. The AL-41F powered the Mikoyan MFI fighter (Project/Article 1.44). Later versions of the PAK FA will use a completely new engine (17.5 ton thrust each), developed by NPO Saturn or FGUP MMPP Salyut.
If this is true it would seem the Pak Fa (say that 5 times fast

) is much more well rounded than the F22 ended up, and evidently at a fraction of the price.
For some reason I prefer Russian aircraft than American/NATO. Dunno why.
Personally I prefer them for their appearence, comparing previous generation aircraft (su-27 with the f-16 for example), the american designs seem much more blocky, while the fulcrums and flankers were very smooth (not to mention pretty dangerous up close).
