Lean (Quant Connect) vs. Zipline-reloaded

Hi Stefan & Community,
I recently purchased the ML for trading book and have found that Quantopian is shut down and therefore Zipline is no longer supported. I see that there is a Zipline library that has been updated by you Stefan, to work with updated versions of python. However as I am only now beginning the code for my machine learning program, I am wondering if it would make more sense for me to use LEAN with Quantconnect as it is being maintaned by a company and I don’t have to be as concerned that the library that I am using will cease to be maintained after I write my code. Is this a reasonable concern? Besides the obvious benefit of having the code samples that Stefan has written, are there functional bennefits to using Zipline over Quantconnect’s Lean? If so what are they?
