Detailing Characters & Settings: Is More Less Better Than More?

In the collection of conversations I’ve had around the topic of character & setting details in a literary work, I have heard an overwhelming response of folks in favor of authors who provide vast amounts of detail when describing a character’s physical description. And the same goes for a setting if its a key location (such as the town or street where a character lives, a room where important pieces of the story take place, etc).  For example, chapters 1 -3 of The Diamond Thieves well-depicts the main characters physical description and personalities. This is especially important since they are identical twins yet extremely different personality-wise. I have only heard of readers preferring that a character be more left up to that reader’s imagination for minor more utility role characters & places in a book.  The beginning chapters also provide an abundance of visual imagery to describe the small, fictional, Southern town of Eugene, Mississippi.
