Hi Seymour,
You are certainly looking at great choices and when you are down to the final stages of “good vs good” then it really comes down to the objective, subjective, and intangible difference that are most important to you based on your own personal value equation. There really isn’t a “better or worse” choice at this point … only best for each of you.
While I don’t help people make final choices about what mattress to choose other than helping to eliminate options where one is clearly worse or perhaps more “risky” than another (which isn’t the case here) … post #2 here and post #2 here, and post #136 here (along with the previous link about your “value equation”) may help you with how to choose between two quite different choices where there is no clear “better or worse”.
At this point nobody else can really say which one is “best” for anyone but themselves and either way you have some great options and some “difficult” tradeoffs between them 
If its any comfort … just imagine all the people buying mattresses who have final choices between “poor and poor” and both they and the salespeople they are dealing with don’t know it. There are no “mistakes” in terms or quality and value in any of your choices.
