It's not known yet. PAK FA is about to be a multirole machine (attack aerial, ground and naval targets) thus it may carry a 30-mm cannon like Su-27/Su-30 (GSh-301 or its successors), Next Gen. of Russian AA-missiles from long to short range, Air-to-surface missiles, unguided missiles, guided and unguided bombs... Precise weapon load will strongly differ upon the current (future) aims of a PAK-FA squadron...
If RAF refers to Russian air force, then yes, they have built one by the name Sukhoi PAK FA t50 . The name of the Indian version would be Sukhoi-HAL FGFA. (Sukhoi Hindustan Aeronautics Limited Fifth Generation Fighter Aircraft).
If you meant by technology,then it would be either the F-22 Raptor,F-35 Lightning II, or the new Russian PAK FA,but if you meant by service record,then it would be F-15 Eagle,having scored 104 air-to-air kills for no losses
They appear (I say "appear" because there is very little information available on the J-20 at the moment) to be designed for different rôles. The PAK-FA is a fighter in the tradition of, say, the F-22, while the J-20 seems to be more of a light, supersonic, bomber.Neither of them are, so far, operational aircraft and neither are anything more than airframes with engines and a lot of test equipment. They carry no weapons and no radar.It's impossible to say until1) they become operational aircraft AND2) they actually get to do the job they are intended for.And even then (IF they are intended for different rôles) how do you you compare them?Is the F-15 better than the F-111 (to give [possibly similar] examples)?
Currently it appears that India has no indigenous stealth fighter design. It is, however, working in conjunction with Sukhoi to develop the PAK-FA/ T-50 into the Indian FGFA.

Basically it's not known.It's intended to induct the T-50 (also known as the PAK-FA and as the FGFA in India) in 2017, but much development work needs to be done.So far only three airframes have flown and none have them have been anything more than development/ test aircraft (no weapons, no radar etc.).
