How is Adlerian psychology regarded professionally? How common is it’s practice versus Freud’s theories in therapy?

I’m reading The Courage to be Disliked and it preaches the value of Adler’s ideas, often in opposition to Freud’s theories. I definitely see the value and have been convinced by many of the arguments, but I’d love to know in academia and professional therapies, how do experts and practitioners actually value these theories? Is there evidence for or against its legitimacy? Just wanting to have some more perspective on it. Thanks!

The vast majority of the things that both Adler and Freud thought are rejected by professionals in the field. In fact the vast majority of all original psychoanalytic thought is not considered science at all.

Karl Popper offered a definitive critique of both Adler and Freud in 
SCIENCE: CONJECTURES AND REFUTATIONS. The main argument is that these theories are unfalsifiable -- that is, there is no way to test whether they are true.  Thus, while they may have intuitive appeal, so do horoscopes.
