With mattresses, the only golden rule is that no one else's recommendation should matter to you. It really is a personal choice – a function of sleeping position(s), BMI, gender, preferred feel (in<->on), and other considerations (back issues, motion, heat, etc.).
This is actually scientifically verified: https://www.rti.org/sites/default/files/resources/rr-0016-11.... As they put it: "The actigraphically best mattress was well distributed among the sample of participants and across the seven mattresses studied." Basically, there was no "mode" best mattress. No one else's experience applies to you.
They also note that "The mattress that individuals chose as optimal before the randomized, controlled phase of the study did not predict either the actigraphically determined best mattress or the best mattress as determined by reported sleep quality." My take: focus on in-home testing, trying to understand what you like, and return policies more than showroom tests or recommendations.
