Hi MentholRum,
Dreamfoam is a member of this site which means that they compete well with the best in the country in terms of their quality, value, and service. Both of these would be good quality and value choices but they are really apples to oranges comparisons because latex and memory foam are very different materials (almost as opposite as two foam materials can be). You can read more about how they compare (even though they really don’t) in post #2 here.
Both Dreamfoam and other people have said that the 13" gel memory foam is similar in terms of “feel” to the Tempurpedic Cloud Luxe except perhaps a little firmer so it you test the Cloud Luxe locally using the testing guidelines in post #1 here you will have an idea of how well it matches your specific needs and preferences in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences).
Sleeping on a latex comfort layer is a very different animal compared to memory foam and I would suggest that you test some Talalay latex mattresses locally to get some familiarity with the material and how it feels and performs. If you decide to go in this direction then I would suggest a more detailed conversation with them on the phone so they can help you with the firmness choice that may work best for you based on the averages of their customers that have a similar body type, sleeping positions and preferences.
If you have a strong preference for latex or memory foam when you test both materials that will help you eliminate one or the other although the gel foam would still need to be suitable for your body type and sleeping style while with the latex you can choose a custom firmness level.
