I've never seen a psychiatrist as a patient but know many via work. Ideally, I would prefer someone who does therapy but has scientific/medical training, so probably a psychiatrist who is also trained in and does therapy. I like those that are aware and reasonably knowledgeable about how psychological features have physical origins, that the way an early life experience leads to long-term issues is not something mysterious but works via physical mechanisms. My last T was a social worker who had quite a lot of training and work experience in neuroscience, and that made him initially highly appealing. I found his science knowledge rather outdated though in reality.
