Depends on your background and what you're most interested in learning. - if you want to really understand the mathematical foundations, you should take Andrew Ng's course (the full Stanford course not the Coursera one) - If you want a quick sampler of ML and to know the big ideas without investing too much time, take Andrew Ng's coursera course. I'm not sure what his deeplearning.ai course is like but it seems like that one is in python. - if you want to learn by getting your hands dirty, either fast.ai's ML course or Dive into Deep Learning is good. Fast.ai's course will get you into the nitty gritty parts of training neural networks.
