PyTorch is great, its honestly much easier to use than TensorFlow, especially for beginners. TensorFlow however offers everything PyTorch does through heavy use of object oriented design (primarily inheritance).

The functional model in TensorFlow is very similar to the default way of instantiating models in PyTorch. TensorFlow has both many many convenience wrappers but also gives you the full freedom that PyTorch does, given that you are able to deal with the nuances and complexities of object-oriented design and refer heavily to the documentation.
