I can attest to PCG being fantastic. Not only is the algorithm fast for one-off generation (the GNU GSL is quite slow comparatively and MKL is designed more for vectors of random numbers) but the API is really well designed. Anyone doing monte carlo simulations in C/C++ will really appreciate using it.

The TL;DR seems to be "mathematically 50/50 chance that PCG is better than others, but for certain cases it might be superior."
