Tensorflow Meets PyTorch
This is Medium toll-gated but worth a good read. PyTorch rules them all these days and rightfully so.
Whether eager execution makes your program is a little slower or a lot slower depends on how much of your computation is spent in high arithmetic intensity ops like conv or matmul.
IE, doing pure matrix multiplications (longer than 1 millisecond) is not much different whether you use TensorFlow eager, PyTorch or TensorFlow classic.
