Regarding expressing anger (or just dissatisfaction) directly and constructively - I guess that's what learning to be more assertive implies. I think it is a skill definitely worth working on and I personally believe it is easier to practice with someone who is quite direct and honest rather than someone who wants to please you and use subtle emotional manipulation to change your anger. It is not all bad not coming back aggressively to people's opinions and feedback though. In a way, I think this is also why your posts here interest many people and why people actually express their varied opinions to you, because you rarely become very defensive, unfair and dismissive (some other posters do and that's usually the end of any constructive discussion). It creates an impression that you are quite open-minded and receptive - I imagine your T shares what's on his mind also at least partially because he sees these features. It's like it's actually worth the time and energy to give you detailed feedback vs. to someone who would not even listen or would straight reject it. I think it makes you quite appealing to communicate with. Well that, plus your own detailed, authentic expressions and the depth with which you approach things. Of course it can hurt to be so vulnerable because you do not escape and detach from your feelings as a defense - that's what I tend to do, for example. I believe somewhere in the middle is the best compromise.

I also very much agree with susannah about everyone's projections (I think I said similar before). For example, I often hesitate to respond because I am aware of a strong bias I have for your T and don't want to say things that are primarily motivated by wanting to defend someone/something I subjectively like and think it would work for me. It is actually quite interesting because I tend to be pretty critical about therapy and Ts in general, the bias is clear. I was also going to say that, ultimately, the quality/outcome of therapy is to be measured by what sorts of improvements it leads to in your life rather than how you feel in a given moment... but I am not sure that is correct for everyone. I guess you already know what it's like to have a T who is more warm and fuzzy and thus more satisfying in the moment - the question is whether it is associated with other qualities and improvements. I doubt that a perfect T exists, so all of them will have traits that are appealing/useful and others less so. I would ask myself what are the things most important for me to have a more fulfilling life and better mental balance, and who is the most likely to provide that or help you achieve that. If you are unsure, I would experiment more and make conclusions from varied experience. You could indeed interview a few more Ts and maybe see another one for a while that seem to satisfy you in different ways - see what happens, why not? I don't think clients need to be loyal to Ts in ways we are to other people in life, in "ordinary" relationships... maybe better to be loyal to your own genuine needs and life goals. And I also don't think warm and fuzzy behavior has much to do with someone's boundaries and effectiveness unless they are warm and fuzzy as a manipulation tactic, not because that's their genuine personality. I have met plenty of people I would describe as warm and fuzzy, who also had excellent, healthy boundaries and self-confidence... and many people who appear quite detached and hesitant to engage not because they have good boundaries but because they are highly avoidant and insecure. Ultimately, in professional contexts, I usually prefer whatever/whoever is most constructive and contributes productively. In many ways, I think my own therapy was not very useful in the past because I choose Ts who were not very compatible with me for the sake of larger goals and did not contribute much in that sense. One of them was very pleasant but little else, they just did not challenge me or not in ways appropriate and helpful for me. But if your primary need is to feel cared for in more personal ways and to have unconditional support, then you can choose with keeping those needs and qualities in mind. I agree with your T and others here that it has to be your decision, everything else is just opinions a suggestions.
