I love both my ebooks and my audiobooks. But if I had to choose one it would be my ebooks. I feel you are more in control with your ebooks as with audiobooks you are at the mercy of the narrator and sometimes that is not a bad thing. But there are parts you can skim through with an ebook or pbook whereas with an audiobook, unless you know where you want to go in the book and the audiobook is broken up in chapters (some are, some aren't) you have to muddle through some parts that you really don't want to listen to.
I listen to my audiobooks during my commute to the train station and when I am working on something mundane and vegetative @ the office. I read my ebooks on the train, during lunch and every other spare minute I have!
