(but both are great)
Sorry, not even close for me.
Andreas is a great speaker for BTC, clearly comfortable with public speaking. However, most of the time you need to catch him on his terms. Whereas that other guy designs his material with the reader/listener/viewer in mind, so much so that he anticipates questions and puts them in the material so that you get to experience the material from an additional perspective.
I suppose what I'm saying is Andreas does more lectures and the other guy does more teaching. Both are experts, you can learn from both, however I believe I could learn far more, in less time, using less energy, learning from James.
