Cities of the Red Night is certainly very readable and digestible but imo, it isn't that far removed from the Naked Lunch, especially when compared to the Soft Machine or Nova Express, the latter of which verges on unreadable.
Naked Lunch wasn't ostensibly made with the cut-up technique anyway, as was noted above, it was more that it was put together by other people using sections of what Bill had scribed whilst off his tree and making into a wonderful book, a wierd read and a deeply humorous episode.
