Additional Math 0606: best course book

I need to choose which coursebook I will use to learn Add Math.
As far as I can see, there are 4 possibilities:
- Collins
- Cambridge University Press
- Hodder
- Marshall
Any feedback on any one of these?
Thanks!

If you're talking about OCR FSMQ Add Maths, then the textbook my school lent to me was the one by Hodder Education.
I found it useful going over the examples and the textbook was quite detailed from what I remember. I believe it has practice questions in it as well.
Hope this helps!

Thanks for your answer, but I was talking about IGCSE Additional Math 0606 (sorry, should have been clearer).
