Somehow I can never take somebody seriously who says "this is the best". How can you know it is the best book? Have you literally read all of them and can thus compare them? If not, how can you be sure? Is there even such a thing as a best book? Different people have different backgrounds, learn in different ways, like different things. Why would there not be multiple "best" books?

Reminds me of a guy I once met, who told me that "this is the best bakery in the city" (>1.5e6 inhabitants). Interestingly, the city's best bakery was just around the corner of his appartment. Once he moved to a different appartment in 10min walking distance, he never went back to the best bakery. He found out that the bakeries closer to his new appartment were at least equally good...

There aren’t that many econ textbooks. The others are all trying to do the same thing, stuck in the past in different ways.
