Hi scg,
This would depend entirely on how all the layers interact together (the firmness of the base layer and the thickness and firmness of the comfort layer) and with your body and which one your testing (using the testing guidelines) indicates is the best “match” for you in terms of PPP (see mattress firmness/comfort levels in post #2 here). This isn’t a “better/worse” choice but a choice between which one is “best for you”.
