Hi Ramos,
Neither of the mattresses you are considering have any weak links in their construction and both use good quality materials (5 lb or higher density memory foam in the comfort layers and good quality polyfoam in the other layers) so in terms of quality they would be well worth considering.
Of course you will need to talk with them about how suitable either mattress may be for you in terms of PPP because you won’t be able to test them in person and the return policies may also be an important part of your personal value equation if in spite of the “best efforts” of both you and the manufacturer you end up choosing a mattress that doesn’t work as well for you as you hoped but they are both in a good quality / value range and would be a final choice between good and good (see post #2 here).
