I don't have experience with any of those, but I see you have a slaatva latex in your list and I purchased a Sleep EZ latex mattress 2 years ago. Prior I had a memory foam from a company called Isoform Bergad who no longer makes mattresses. The memory foam was ridiculously comfortable to sleep in, it formed to your back perfectly. But edge support was horrendous, and while having sex it was literally working against you. I think the latex is a good compromise, it has more springiness and more edge support, while still contouring to your body better than a spring mattress.
