I never said all others first of all, I just know that's one example I have a lot of positive firsthand experience with. Generally as well it's not like curriculum approaches have any evidence either way, so while there may not be evidence, I would ask what curriculum does have evidence that it's better than another. I've done some digging explicitly in that area and there's really no good evidence for anything from language choice, object oriented vs functional, everything. Not surprisingly either, it's quite the hard problem to solve and get rid of bias towards one approach in a study to start with. I'd say this though - a "cult" following I would note as a likely symptom of a good curriculum, one that does such a good job that it inspires those that go through it to advocate for it strongly. Is that not itself evidence of some indirect sort? I'd say it's better than most out there. In terms of its advantages, I think a reasonable person can decide if both the advantage is actually an advantage and at least gauge how a curriculum fares on executing on the advantage. For example, the ramping up of difficulty from the teaching languages. Instead of saying "theres little evidence", I would go through the curriculum and its advantages (and disadvantages) like that.
