Are “best” and “favorite” the same thing? If someone asked you “What’s the best book you ever read?” would the answer be the same as for “What’s your favorite?”
Not necessarily. Many of my favorite reads are not the best, most well-written books on the planet, but I've connected with them in an emotional level that has nothing to do with how they rate. My favorite book, however, is Crime and Punishment, one I do think is one of the best books written, so it can go both ways.
