Hi Jtat84,
It sounds like you’ve done some very good research and none of your choices have any lower quality materials or “weak links” in their design.
There is a little more about innerspring/latex hybrids vs an all latex mattress in post #13 here but this is really a preference choice and one wouldn’t be “better” than the other.
When you are down to finalists that are all choices between “good and good” and none of them have any weak links or lower quality materials in their design and if there are no clear winners between them then you are in the fortunate position that any of them would likely be a suitable choice and post #2 here can help you make a final choice based on your local testing, your conversations with each of them, your confidence about the suitability of each one, the prices, the exchange or return options you have after a purchase, any additional extras that are part of each purchase, and on “informed best judgement” based on all the other objective, subjective, and intangible parts of your personal value equation that are most important to you.
The goal of good research is to reach the point where you have a few finalists that would all make good choices and where your final choice is “difficult” … which it sounds like you have … but the final choice is something that only each person can decide for themselves. There are certainly no cautions or warning signs that I can see with either of them.
