Disclaimer: I write competing software to tensorflow and compete with google cloud which commercializes tensorflow.

So let me turn this on its head. Why does it matter? Use what you find works for you. If you already know the concepts, what's stopping you from just using pytorch for now?

I would suggest stepping back and asking yourself that first. Don't learn something "cuz hype".

Granted, TF has the new eager api that just came out. That might help you?
