If they are producing 100 J-20 per year, then they should be able to make 600 more J-20 by 2030, combined with 300 J20 that they have now, that's about 900 J-20. So, kinda close to a thousand. I do believe China will keep producing J-20 in high numbers because they have chosen J-20 to be the main fighter for the foreseeble future. I don't think PLAAF will go for a hi lo mix. They are probably going all in on the J-20. So, their final J-20 count could only be extremely high.
This is assuming production doesn't slow down. Realistically they'll probably think ~600 is enough (for example) and slow down

The two does not have similar degree of stealth method used. One thing of stealth is the facade to be flat so EM waves bounce off to other directions. F-35 has a bumpy under belly like a conventional aircraft. Being larger isn't nacessarlity a negative thing for stealth, example is B-2. It is also worth to note that F-35 was not designed to match the level of stealthness as F-22 from its inception and will never reach that level.

Bigger radar is certainly better if others are equal such as SW. And no need to argue about F-35 has any advantage in radar software, software is nothing except the algorithm which US doesn't have edges. The mobile network essentially shares the same knowledge and exprience with radar signal processing, guess who is the leader in the area.
B-2 is an entirely different design though. Bigger doesn't mean worse but it does pose extra challenge. Being smaller quite literally means you have a smaller RCS to start off on. F-35 may be less stealthy than F-22 but that's an extremely high bar to set in the first place.

I understand China is very much in the leading edge of the technology but it's always wise to overestimate your foes instead of the other way around. US has a ton of exposure and has been gathering tons of intelligence on electronic signatures around the world. This is a huge advantage especially since it helps them narrow down specific signatures in a noisy environment.

I am just playing devil's advocate but I really do think there's should be some more caution in comparing the J-20 to F-35 especially if we claim it's better than the F-35.

No way they will think just 600 will be enough if US plans to have 2000 F-35. China also needs to take into account the Air forces of Japan, Sk, Taiwan and Australia. China needs to have at least equal number of planes than US and its allies. Ideally it should overmatch it if it intends to force US out of West Pacific without a fight. Only massive numbers and quality can do that.

I think China will eventually have around 1500-2000 J-20 in the future. But I don't think all of them will be Air Superiority variant of the J-20. They will eventually move towards a Fighter-Bomber/Multirole version of the J-20 with more focus on ground strikes. Maybe the twin seater J-20 will focus on that in the future.

I expect these twin seater J-20 to eventually replace the Ground strike focused flankers in the PLA.

So after 1000 J-20 the rest of J-20 will focus on ground strike while Air superiority mission will be given to the 6th Gen fighter China comes up with.

It is worth to note that PLA planned J-20 to be both strong in air superiority and long range ground attack (not F-35 kind of bomb truck but long range ground attack missile). It is also worth to note that J-20 is aimed to be slightly more expensive than Su-27 that China imported in the 1990s. PLAAF also concluded that heavy fighter has higher capability/price ratio (性价比) than light/medium fighter, that is why J-31 remains a wish for the moment and its chance of taking up J-20's number is very low. J-20 is fulfilling most if not all mission profiles of F-22 and F-35/FC-31, the number of J-20 to be built will be very large, neither is cost an issue.

I think CCAs are where China will really press it's manufacturing muscle and amplify the newer J-20 variants capabilities, especially within the first island chain.

So are J20 with the WS15 engines now a standardized thing?

If so, its weird how it just happened and not much noise was made out of it.
