I don't think there is any reason to change implant brands looking for a different shape if they are both going to be round. The main difference you'll find between companies is the cohesiveness of the gel, the overall feel of the implant, and the customer service and warranty differences.
You state that you are looking for a rounder upper pole of the breast and are wondering whether Mentor round implants will give you more upper pole fullness than a Sientra round implant. The answer is no. Upper pole fullness can be achieved by either implant. It is a factor determined by how large the implant is for YOUR available tissue (in other words, the tighter your tissue is around the implant, the more upper pole fullness you will see), and the shape of the implant (round implants from either company tend to produce more upper pole fullness than shaped implants, unless the round implants are small in relation to the patient's tissues and thus not tight in the pocket). You do not show a photo of your current result, but if you want a result with more upper pole fullness, as in the "goal" photo you show, then your surgeon must use a larger implant, but it is important that the implant width not exceed your breast width or you may develop problems in the future.
I have been offering Sientra implants for over 9 months. I do not believe there is any major difference in how they look unless you have the Sientra anatomic-shaped implants which would give you less upper fullness. I offer them and use them predominantly because of the lower rupture rate when compared to the other companies rates and lower risk of capsular contracture with the Sientra textured implant.
If you are looking for a rounder upper pole, I don't think a Sientra anatomic implant would be a good choice for you - they distribute most of their volume to the lower breast pole.
Great question. Upper pole
fullness is a common concern when it comes to choosing which implants work best
for your body, and many women are on the fence in regards to brand and size.
Achieving the volume and fullness you're looking for in the upper pole is best
accomplished with round implants rather than shaped implants. However, keep in
mind that breast augmentation can't necessarily alter your natural breast
shape. Your anatomy will still have the biggest influence on how much upper
pole fullness you achieve rather than the implant you use.

As long as you compare like to like, the appearance will be the same. In other words, it has to be the same volume and projection (moderate plus to moderate plus, high to high). Aside from that, the main thing I have noticed with the Sientra implant, is less rippling, even though rippling is not common with any silicone implant. The Sientra round implant is the only one with the 5th generation highly cohesive silicone, a true gummy bear round implant. Both manufacturers make a nice implant.

Sientra, Mentor, and Allergan all produce very high quality implants that are FDA approved in the United States. It is possible to achieve very similar results in terms of shape with each company. There are differences in the texture of the gel between companies, and minor differences in the shapes and sizes offered. Your desire for upper pole fullness is achievable with any of these companies.
Without seeing preop photos and performing an examination it is difficult to recommend a size and style of implant, but I would consider a moderate plus profile as sometimes the wider base diameter provides more upper pole fullness.
The answer to your question is no, there really isn't any difference in the shape between manufacturers as long as you are comparing similar implants. For example, both companies make smooth round high profile implants that look very similar. We can expect very similar results in any given patient.
There are small variations in breast implant dimensions, but for the most part, you can get the same breast contour and volume with each. The difference is mainly in the viscosity of the implant gel.
