There doesn't seem to be much research that shows that any particular kind of therapy is better than others, it seems like most of what I have seen says that the most important thing is the therapeutic alliance.

There also is not much research that shows that meds help.

I've tried meds, they don't work for me. But I believe that they help some people. Same goes for DBT, CBT, psychoanalysis etc.

T3 says that brain spotting combines EMDR and Somatic Experiencing. I find that to be an accurate description.
