Not sure if this is the right place, but came across this latest estimate of the PRC vs US fighter forces and their composition. I'm not quite sure what to make of the GaN AESA figures for China (does this mean that most pre-2020 built fighters such as J-20, J-16 etc. have GaAs AESA?), but perhaps more knowledgeable folks have a better idea.

I'm not sure about those fleet size estimates, some of them (like J-20A/S, J-35 and J-35A) seem somewhat high.
The breakdown of certain aircraft types also seems far too detailed. I'm also not the original OP tabulating the numbers is and why they are worth discussing.
However, to answer your question about GaN and GaA -- well yes, we know that the recent fighter types and variants (J-20A, J-20S, J-35/A likely as well) or batches (such as J-16, probably J-16D J-15T, J-15DT) produced for the PLA should be using GaN AESAs.
Fighter aircraft with AESAs (J-20, J-16, J-10C, among others) that were produced for multiple years in the 2010s prior to the most recent types, of course would be using GaA AESAs given its the antecedent technology prior to GaN, I don't see how that is a matter of confusion.
