Europen sleep works vs tempur pedic vs marriott mattresses

Our current mattress give my husband middle back pains and we want to switch our mattress. The middle part of our current mattress sank in in 3 years. It was a $2k beautyrest mattress which we rotated a year ago. We are 350 lb and 135 lb but prefer to sleep on the same mattress.

We couldnt decide between the two following options and wondering if anyone in similar situation with us has any experience with these mattresses in terms of durability and back support/pain relief:

European sleepworks: talalay latex + basecoils+microcoils

Tempurpedic luxeadapt: tempur APR + foam

Marriott: foam + innerspring
