In the list you've put forth, The Color Purple, definitely.
Not on the list, I saw "Natasha, Pierre and the Great Comet of 1812" yesterday and it was a stunning theater experience. In terms of originality, it's 2016's Hamilton. Not that I'm comparing the two shows, just how unique they are in the innovation they bring to Broadway. You may or may not love it, but it's certainly worth seeing for the experience of it.
I saw "Book of Mormon" years ago in previews and enjoyed it overall, but not enough to see it again. Not a fan of the cringe-worthy scatological humor.
