The Pooleys ones are available to buy as eBooks, but the Pratt / AFE ones don't appear to be.
Can't really help you out on the question of which is better as I used the (printed) AFE ones. Passed all the exams first time with > 90% though so they can't be that bad
Incidentally, I note from your previous posts that you are near EGNX. If you want any advice as to what it's like learning there then let me know. I obtained my PPL there last year and have just completed my night rating there too.
