What are the best deep learning frameworks?

I’m looking to get insights on the best deep learning frameworks currently available. Could you share your experiences and recommendations regarding performance, ease of use, and community support for frameworks like TensorFlow, PyTorch, and others? Thank you!

With the relatively small amount of experience I’ve had…
I have found mxnet easier to use than TF.
The mxnet documentation seems reasonable but the community support is lacking as mxnet has low popularity.
