Calvert's most recent edition has a definite spin of "white people are bad" --not that the long history of racial injustice in this state should be ignored, far from it. But you can very much tell that De Leon (Back to Aztlan) has brought in a definite flavor to it. (Calvert's been dead a while, so it's really De Leon and Cantrell doing the revisions and additional materials.)
I still assign Calvert as my main text, though, because a) it's less expensive and a bit easier to get through than Campbell's GTT, b) it's pretty comprehensive all the same, moreso than de la Peña's textbook, and c) it has superior ancillary materials (test bank quizzes!) to its competitors.
The one that Adrian Anderson co-authored is prety good, though; if his publisher can come up with some decent ancillaries, I might switch over to it.
