- Vigna claims small differences in internal states don't have avalanche effects, and the rebuttal says those small differences in internal states don't occur normally, not with the proper seeding steps.

- Vigna claims to be able to predict one particular variant of PCG, and the rebuttal said that that was one of the weaker variants that specifically has "insecure" in the name.

It's persuasive to me in suggesting that Vigna's claims are perhaps not that clear cut.

I am not an expert in PRNG and I wouldn't say this makes PCG win over Xorshiro or not, I just think it's unfortunate that the issue above linked only one side of the argument, especially since I find the other side more pleasant to read.
