It has the same wing area as the F-35C (and Flanker). See it as a twin engined F35C with better L/D ratio for better supersonic/transonic performance with most likely equal (combat) range.
J-35 only carry A2A munition internally if I'm not mistaken, meaning air superiority focus compare to F35C strike focus.
It's two very different approach for VLO platform and doctrine.
IMO, in the era of stealth, mid-sizes jet due to space constraint can't do both in highly contested environment.
That's why I'm don't see J-35 "as a twin engined F35C with better L/D ratio for better supersonic/transonic performance" but more like F-22 not only in roles(air superiority) but given 93% of the length, same general layout and advancement in manufacture, material, engine; it could somewhat match the performance too.
Say 14000kg empty weight and 11 ton thrust for WS-19 then T/W ratio is close to F-22.
If that's the case, land version of J-35, say J-31 with reduce weight could be as potent as F-22 not to mention better sensor & avionics.
