When you are quickly scanning through a book for information (not a specific word, but ideas like what the plot is), a big page is a big advantage. When you are looking above to refresh your memory ("who is this jim character?") a big page is a great help.

If I am trying to quickly go thru a book for basic information, I will pick a physical book every time, UNLESS I am looking for a specific string, like someone's name. It is just so fast with a physical book to find the next chapter, then flip back to the beginning of the book, then check the last line, etc.
