It really depends on what your model is doing. For a time, sequence models were easier to do with Pytorch than TF (due to control flow). On the efficiency side, for vanilla CV models, I also did not observe major differences last time I looked, but when I started to do lots of things in parallel, multi-gpu training, heavy data augmentation, I think TF has some well-engineered capabilities that are not matched yet.
