Hi grandeson,
None of their mattresses have any lower quality materials or weak links in their design so durability wouldn’t be a concern with either of them.
There is more about the most important parts of the “value” of a mattress purchase in post #13 here that can help you make more meaningful comparisons between mattresses. The choice between the innerspring/latex hybrid and the polyfoam/latex hybrid would really be a preference and budget choice not so much a “better/worse” choice. I would also make sure that you test both mattresses with both of you on the mattress for motion separation because the innerspring may transfer more motion than the all foam mattress which may be important to you.
