How good is China's J8II Finback?

I looked through the old posts and archives but only found one
that mentioned this aircraft in the subject. So I figure
you guys wouldn’t mind me asking another dumb question about J8.

It has very low aspect ratio, I think only Mirage 2000 is lower.
This means supersonic performance and acceleration are good.
Roll rates should be nice, but turn rate would be bad (like SOC
mentioned in the old post). The Delta wings give it large
lifting area, therefore relatively low wing loading. Thrust to
weight ratio is close to F/A-18. As for g limit, I have seen
other sources saying that J8II could sustain a 6.9g turn at
1000m(3200ft) and Mach 0.9. (Can anyone confirm this?)

Supposedly, it’s fitted with Zhuk radar, and it’ll be able to
carry R27R and R73. PL-7 is a copy of Magic, PL-2 is a copy of
AA-2.

I know without context, comparing different aircrafts is
meaningless, but I still want to know, roughly how good is
J8II compare to India or Taiwan’s fighters? (For examples,
J8II attacking Taiwan and get into combat with F-CK-1,
Mirage2000; or J8II against LCA, MiG29, MiG23… so on)

Any replies or correction would be appreciated. And if you
have detail info. on J8II please post it, thank you.
