Temper vs posturepedic

Split between a temperpedic proadapt hybrid and a sealy posturepedic plus hybrid firm.

I'm male, side sleeper, 170 lbs, and coming from a traditional innerspring firm pillowtop serta. Try not to let the firm pillowtop fool you though. I have barely had any goods nights with it.

I've tried both the temper and sealy out extensively at mattress firm. The temper is more unique in feel to me whereas the sealy is somewhat familiar. They both feel very similar though with the sealy feeling a bit softer/more responsive. The sealy is a fair bit cheaper (~1K less), but I've been told it won't hold up as well as the temper would long term.
