It`s possible the J-10 could beat a Su-30SM or Su-30MKI, it was proven the F-18 could beat from time to time the thrus vector capability X-31, however it was verily rare.
Now adding a good off bored missile and a good HMS, the J-10 can increase the odds, but the Su-30SM also has a HMS and high offbored missiles.
- RVV-MD short-range close - in highly dogfight air - borne guided missile is oriented to weapon modern fighters and advanced multirole fighters, battle-planes and combat helicopters. In comparison with its predecessor (R-73E) new missile has extended-range of flight, high-maneuverable performance, jamming immunity (including optical), angle - elevation. The missile has all-aspect passive IR guidance (two-color detector) with combined aerogasdynamic control;
- RVV-SD medium-range guidance missile is intended to weapon modern fighters and advanced multipurpose fighters. With launch range up to 110 km RVV-SD missile is able to engage targets with overload up to 12 g at any time of day or night, in all aspects, in jamming coverage conditions, on ground and water surface, including multiple channels firing in a launch and forget way. The missile feature is inertial guidance system with radio correction and with active radar seeker;
So pretty much they could be even if both are armed with offbored missiles, thus jamming and stealth will play the most important part to decide who is the winner, but here is the difference of Su-35, Su-35 can supercruise so it will first use BVR missiles and speed to decimate J-10s, see Su-35 can detect targets of 3 square meters up to 400km, so a J-10 more or less will be detected at a pretty good range
They [the F-22s] always start defensive as you might imagine because anything else is kind of a waste of gas. So the F-22 always start defensive. On rare occasions the F-22 guy -- first of all, the [F-15] Eagle guy, you have to fly a perfect lag fight (flight?). You have to have AIM-9X and JHMCS [joint helmet mounted cueing system] to get an off-boresight IR [infrared] capability. And the F-22 guy has to put up his power a nanosecond too early and not use his countermeasures and you may get a fleeting, one nanosecond AIM-9X shot, and that's about it."
