The Natrelle 410 seems to have a better shape but it is feels more firm than the Sientra. But the Sientra seems to fold and ripple more easily than the Natrelle 410, at least when being held. Is the softer feel better and maybe the Sientras don't ripple than much when in the body, or does the stiffer Natrelle create a better look when there is no breast tissue to provide coverage of the implant.

Shaped implants and the reconstructed breast.
The difference between the implants is not drastic and they both are likely to give similar results. An important aspect in reconstruction depends on how the reconstruction is performed. Shaped implants require a form-fitting pocket to allow for adhesion of the implant to the pocket to prevent rotation. In a single stage reconstruction with acellular dermal matrix, this can be achieved because the capsule will form around the shaped implant. However, concern exists when using a tissue expander prior to exchange to a shaped implant. The capsule has already formed and there is no guarantee that adherence to the new implant will occur. The implant space should also be fairly tight around the shaped implant to help prevent rotation. The lower pole with shaped implants does have a lower propensity to ripple, but the implants are firmer overall than the round cohesive gels.
Sientra and Allergan 410
Both of these implants are improvements over the round implants, in my opinion. When you stand the three upright (round, Sientra, Allergan 410) there is progressively less deformity and folding. The difference between the Sientra and the Allergn 410 is not as dramatic as their difference with the round. In petite patients, particularly, the anatomic can provide a better shape on the upper breast. I personally feel the folding difference between the Sientra and 410 is not as significant inside the body when the pocket is a good fit, but the density an weight difference remains a consideration.
Allergan 410's and Sientra implants
Both are good implants for reconstruction. They may be a bit firmer than the more traditional gel implants but they may cause less rippling.

The differences you note are less apparent when the implants are placed for reconstruction, as compared to when you hold them in your hand. The best shape for you is determined by your own anatomy. Your surgeon should be able to make a recommendation.

Sientra vs Natrelle shaped textured implants
When used in reconstruction, the differences are so minimal. If you're convinced one is softer and one ripples less, you simply have to choose what could you tolerate more and assuming the implant dimensions are available in both brands, choose the one that would work best for you. Softer? Or less potential for ripple? That is your call.
410 vs Sientra
Both are excellent implants for reconstruction. It is more important to look at your anatomy (i.e. breast width, height, desired projection, etc) to determine which implant is best for you. Both implants result in a more natural look with little to no rippling, especially in reconstruction patients (placed under the muscle). They are firmer than the conventional round silicone implants.
