They're all good, I personally like Aviation Exam explanations and I heard it is more indicated if you are doing your ATPL exams outside of the UK. Don't know why, just word of mouth. Feel free to use one or all of them. And try to study and understand the subjects, not just the question banks.
EXAM 11.0 by Peter's Software is a must if you happen to do your exams in Germany because the Germans want you to fill in the questions. Just saying.
