Without an idea of flying hours for ROCAF and PLAAF pilots it is difficult to even have a rough gauge about how they compare, and we'll have to rely on stereotypes.
However, I think we should consider that a modern air war involves bringing together many different kinds of assets together such as AEWC, EW, ELINT, incorporating offensive counter air and the various elements of strike. You can have a core of pilots who are perfectly trained in their fighters but if they lack AEWC support or are having their communications scrambled by opfor's standoff jammers, then your training in close combat or BVR is not worth as much.
Basically, I'm saying that the training and flight hours of individual pilots isn't necessarily as important as the different types of conditions in which they train under. In that sense, PLAAF has a far superior foundation to train on given their large apparatus of various force multiplier aircraft, and the sheer number of fighters, bombers, and strikers with which they can simulate large air wars with, versus ROCAF whose air fleet is more limited in both quantity and variety.
So outside of quantity, industry, and technology, it is arguably the increasing holistic complexity of PLAAF which is the biggest challenge to ROCAF.

an extreme example demonstrating how training may not reflect capability are the various DACT scenarios pitting new pilots in F-22s against more expereinced and well trained pilots in 4th generation aircraft with F-22 kicking the backside of the better trained and more numerous, well trained pilots. Obviously, the PLAAF/ROCAF discrepancy is not quite the same as pitting 5th generation fighters against 4th generation fighters, but I'm sure I've gotten the gist across.
