Welcome to the Ranch.
I have one simple preference - I always prefer reading materials (hard copies), does not consume battery and can carry with me always.
What is down to the content - we see a lot people here who read that book (your listed item 1) and identified as a good one. I read that book myself - so I could confirm that.
I haven't seen this online course (your listed item 2), so cannot comment on its content.
