Considering it is nothing but a tech demonstrator, it doesn't mean much of anything as APA suggests.

Some Chinese fan boys from another Defense forum said that there are in fact 2 Prototypes of the J-20, one with Al-31s and another with WS-10s.

It has one-piece canopy; T-50 has two piece if I recall correctly
As Legendary Aerospacee engineer Kelly Johnson said:" if it looks good, it flies good."
I think J-20 got the best looking out of all the stealth fighters. Gotta fly good as well.

Electromagnetic radiation, emitted or reflected by the gas turbine exit nozzle contributes significantly to the "signature" of a vehicle. By mounting the exit nozzle within a suitably shaped shroud this signature is reduced. Radar signals are absorbed or diffused by the shroud and infra-red emissions are masked, either by the shroud itself or by cool air ducted by the shroud to pass around the nozzle and the exhaust stream issuing from it. Such an arrangement, by its nature, defines a constraining envelope within which the nozzle must lie in order to be effective. This imposes constraints upon the use of reheat or thrust vectoring of the engine exhaust stream.
Here are comments made by others stating why PAK-FA is not a stealth aircraft.
Features that leap out as being non stealthy on the T-50 include:
- Absence of sawtooth edges on anything but the weapons bay doors
- Absence of edge alignment on skin panels
- Control surface inner edges not aligned with planform edges
- Noisy features like the auxiliary vents on the engine inlets
- Lower fuselage from the inlets rearward is completely conventional, no blending at all of engine nacelles into fuselage
- Upper fuselage from the mid-wing rearward is conventional, no blending of engine nacelles into fuselage (although partially masked from the sides by the empennage)
- Straight-through engine nacelles

Perhaps people making these comments perhaps should reconsider what the term first flying prototype means.
Why show the world what the stealthy aircraft will actually look like 5-10 years before it enters service?
They've got a bomber edge over Russia now as well.
