Hi Pspa123,
There is more information about the general differences between latex and memory foam in post #2 here but in very basic terms latex would be more resilient than memory foam. I would also keep in mind though that both of these pillows don’t use solid layers of latex or memory foam and also have other fibers in the mix that will dramatically change how the latex or memory foam will feel and perform compared to a solid layer of either material so comparing them based on “specs” would be very unreliable.
These types of questions are much too subjective to be able to reliably answer outside of your own personal experience because the only way you will know how they compare for you (regardless of anyone else’s experience or opinions which could be very different from your own) would be based on your own personal experience.
If you can’t test a pillow in person then the most reliable source of guidance about how they may compare would be a more detailed phone conversation with a knowledgeable retailer or manufacturer that would know much more about how they compare based on their own personal experience and on the feedback of many customers than anyone else. I would always avoid emails for these types of more subjective and complex questions (see post #4 here).
