There are many people, especially scholars who are engaged in popularizing aviation knowledge, who have made detailed comparisons between the two models of aircraft. The J-35 has no advantage over the J20 in any aspect. I will compile and translate related articles later.
That is exactly why the PLAAF chose to procure the J-20. The J-35 does has the potential to have a lower overall RCS, which is a plus because it has a smaller radar. The J-20 wins in all other aspects. It is larger and capable of holding more/larger sensors, more fuel, more armament, larger engines etc. The PLAN chose to go with the J-35 because MTOW is limited on an aircraft carrier, so a J-20 would have to take off with less fuel or less weapons or both. The J-35 will cost less to purchase and to operate; therefore, more countries will have access to it.
Personally I doubt that any "scholars" who are truely invested in this kind of debate hold eneough knowledge on the specifics of the 2 models to make a comparison that's trustworthy. The arguement between J20 and J35/J31/FC31 (whichever really, most of the arguements merge them into one) has been longstanding and surprisingly toxic so realistically don't take their points to heart and instead come up with what you think is likely based on what is made open to public.
Not at all necessary，Non-stealth fighters are in front of stealth fighters, not competitive, are turkeys
Whatever new variant of the FC-31 will lose out in terms of payload capacity due to smaller internal bays, avionics will/could/should be a different story, though.
The internal bay of the J-35 is roughly the same as the main bay of the J-20. It just has no side bays.
Easier to move arround in the hangar deck too !
I dont think China cares one way or another right now about what India does or doesnt at this point in time, they're more focused on US and it makes sense for them. Similarly, Pakistan does in a way observe what India does, as it makes sense for them.
