Well, J10's aerodynamic design features are Delta wing + canard,
So, the design itself can give J10 better performance than F16 at
high speed, similar to Mirage2000, remember, Greek AF delta wing
Mirage 2000 usually won over Turkish AF's F16C because of its
better instant turn rate, while Canard in conjunction with digital
FBW, gives superior low speed performance as well, similar to F16
as seen from the video, one also can see from the video, J10's
Instantaneous turn rate probably over 30 degree, better than F16fs
26 deg, overall roll rate > 300 deg, interested one, may use
stopwatch to check, thatfs achieved with 3 fuel tanks + 4 AAMs ( 2
PL8 IR AAM + 2 PL12 MRAAM), it was said at this loading, J10 still
can reach Mach2 while F16 has to be without combat load.
The avionics of J-10 wonft be that bad as well, the glass c-ockpit
of lower tie JF-17 fighter made by the same aircraft company that
also makes J10 actually is comparable to latest F-16
BLK50/52:

JF-17 c-ockpit
However, I will vote F-16's radar is more mature and powerful as it
provides more modes, so nowadays F16 is more a multi-role platform
rather than air superiority one, actually, the all time favorite
superiority ( A2A) F-16 IMO is not the latest blocks but BLK20/30
with MLU. The newer blk F16s although with more powerful engine,
the T/W ratio is dropped rather than increased because of the
multi-role needs.
