I rotate my cookbooks for bedtime reading. I don't find I have any
favorites. I do find that I cook most from what I have read recently OR from
books that I can find my way through easily. Because I know them well, or
because their typography is particularly good. Bad typography can be a
reason for never getting to know a book well, as can bad translations.
All of this is assuming the recipes are good enough, of course.
All in all, I don't think I have answered your question
