My 2 cents: I am still the stubborn minority using TF. Mostly because of switching costs in my organization. But also, honestly, because I am decently happy with it. I think the ease-of-use gap between pytorch and TF was mostly erased with the release of TF2. I was really hoping that more of the research community would come back to TF after that, but unfortunately that has not been the case. In practice, it does suck to not have access to SOTA models. Otherwise, I think they are pretty similar.
