As far as I can tell, CBT is the gold standard for psychotherapy in much the same way that agile is the gold standard for software development. There's compelling evidence that some implementations can be remarkably effective at least some of the time, and a vague consensus that it's good and proven. However, there's also widespread disagreement and confusion about what it means to actually do it, how to evaluate whether it's a poor fit as opposed to the practitioner or client "doing it wrong", and the extent to which it meaningfully outperforms other approaches across a variety of real-world situations.
