150-200cc. Does this profile and size make sense? (photo)

Your wish photos are not B cups, but I suggest not going larger than 250 cc's for you. If you just want to add one cup in size, go with 200 cc's. You will lose some volume with the lift removing excess skin.

Choosing an implant size/style is an important decision which is best made in concert with your surgeon. Ultimately, options are based on a number of factors including:
-Chest dimensions: This point is crucial as the width of your breasts defines the available "real estate" on which the foundation of your augmentation is built. This "foot print" is the absolute limit with which you are dealing. Too "large" is not so much the risk as too "wide." You cannot build a 3 acre mansion on a half acre plot. An implant which is too wide (exceeding the available space on your chest) will generally over hang laterally making it more noticeable and occasionally contributing to discomfort and nerve symptoms (numbness or tingling). This will also contribute to a more unnatural look.
-Tissue quality: This relates to size in the sense that the implant will be suspended by your tissue. Too large an implant may place took large a stress on these suspending tissues leading to healing problems in the short term and bottoming out in the long term.
-Patient desire (what is the look you are hoping to achieve?)
My role as a surgeon is to manage expectations and guide you towards a prudent choice which can satisfy these reasonable goals. Often times, a surgeon can guide a patient toward a size/cc range and patients will make determinations on implant style/profile. Patient seeking more or less projection, or seeking a more pronounced or subtle upper pole volume increase can be guided toward an implant which will help them best achieve their goals. Additionally, technique variations (sub muscular vs. sub glandular) can also aid in obtaining the look you desire.
There are a number of tools available to help guide patient/surgeon decision making including sizers, 3D imaging and goal photos. Each modality can help better communicate your goals to your surgeon and vice versa.
With regards to your specific question, there will always be variations in measurements from one examiner to the next. The take away is that both feel you have a narrower frame (a claim bolstered by your photos). Given the width limitation, a HP device will deliver a more reasonable volume in this more limited space. It is also important to remember that small incremental volume changes rarely dramatically impact the final result (44 ml is a shot glass).
Ultimately, it is important to not marry oneself to a particular "cc" as oppose to a particular "look." Communication is key as you and your surgeon create your custom surgical plan.
As always, discuss your concerns with a board certified plastic surgeon.

I would recommend an implant with a breast lift. This would create volume and reposition the nipple-areola complex over the new breast mound correctly. You need to see a very experienced American Board of Plastic Surgery certified surgeon. Ideally, this surgeon has also completed a fellowship accredited by The Aesthetic Society.
