I personally prefer audobook. This days I hardly able to read a book, before I can finish a chapter I have already reach my stop. And audiobook can allow me to enjoy a book while on a move.
I subscribe to this ikoodos.com, they provide good service and quality audiobooks. And at time have pretty good offers. Like now Agatha Christie's dramatize audiobook at $7.99 only, pretty cool right.

I believe you enjoy it too. Hope that my recommendation help.
