One of my therapists had very messy, confusing and unpredictable boundaries. The other one was quite good with it: consistent, predictable, non-intrusive, professional. I've learned some great lessons from both therapies but liked the consistent, very professional one much better. None of them harmed me in any way but would not say any of them changed my life or made me discover entirely new things about myself. I always felt very free to use them as I wanted to, take what I found useful and leave the rest, never felt they had power over me or something like that. One of them tried for a while but it only led to my dumping him.
