Ask HN: Which Are the 'Good Parts' of the FAANGs?

Every so often an uncomplimentary story comes out about someone's experience working at a FAANG, and HN comments start proliferating about how what TFA describes, while unfortunate, isn't really representative, and working in some other part of the organization is completely different. So, I'm curious: Which are the best parts of these heterogeneous organizations to work at?
