Hi klauser33,
Latex in a suitable softness/firmness level can be as pressure relieving as memory foam but as you know it has completely different properties so they are really an apples to oranges comparison. I would also keep in mind that the primary support for a mattress doesn’t come from the comfort layers but from the deeper layers of a mattress underneath the memory foam (memory foam isn’t used in the deeper support layers of a mattress because it’s too soft) and memory foam mattresses use a different material such as an innerspring, polyfoam, or latex in the support core.
There is also more about primary or “deep” support and secondary or “surface” support and their relationship to firmness and pressure relief and the “roles” of different layers in a mattress in post #2 here and in post #4 here that may also be helpful in clarifying the difference between “support” and “pressure relief” and “feel”.
While every type of material has higher quality and more durable versions and lower quality and less durable versions, assuming that you are only comparing good quality materials the choice of material is really a personal preference issue more than a “better/worse” issue. There is more about the pros and cons of memory foam vs latex in post #2 here but the most reliable way to know which one you tend to prefer in general (or the versions of each one you tend to prefer) will be based on your own personal testing and experience.
