Hi AMG_Roadster,
Hopefully some of the forum members that have seen your post will provide their feedback but one of the goals of this site is to help the members reach a point where they have eliminated all their worst choices and their final choices are all good ones and the decision between them is a difficult one that is more about the subjective or even intangible parts of their personal value equation than it is about any obvious differences in quality and value.
Of course I can’t tell you what to choose or which is “better” because there are no obvious answers and it depends on all the many tradeoffs that are more or less important to different people and circumstances but post #2 here about making final choices may be helpful.
In terms of quality or value you are in the enviable position that there are no “bad” choices or “mistakes” anymore and I only wish that every consumer that was buying a mattress was facing the same difficulty in their final choices as well
