Hi Mikep,
Once you have narrowed down your options to a list of finalists that are all choices between “good and good” (which they are) and you have confirmed that none of them have any lower quality materials or “weak links” in their design relative to your weight range (which they don’t) and if at this point there are no clear winners between them (which is usually a good indication that you have done some good research) 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 or mattresses you have slept well on, your more detailed conversations with each of them, your confidence about PPP and the suitability of each one, their prices, your preferences for different types of materials, the options you have after a purchase to fine tune the mattress or exchange or return the mattress or individual layers, 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.
You are certainly looking at some great quality/value choices and I’m looking forward to finding out what you end up deciding 
Phoenix
