I think it really depends on what you want the relationship to look like. I consider my T a good T because she lets me take therapy at my own pace, yet she knows how to gently nudge me along when I'm stuck. She's very kind and patient, yet she also does reality checks once in awhile when my thinking can be a bit irrational. She's very good with dream interpretation, which I love, because I tend to have very vivid dreams. And she's a very good listener - she's very present in the room with me, I know that I have her undivided attention, and she's been very attuned to my feelings from the start - I don't know how she does that so well, but she does!
Good luck if you are searching for a T! It took me a few tries before I found this one, she's a keeper.
