Hi uptick911,
No … which one provided the best alignment would depend on the specific design and materials of the mattress as a whole so one isn’t “inherently” better than the other although latex has better “point elasticity” which means it can contour to the sleeping profile a little better than an innerspring. They also have a different response curve under pressure. There is more about the differences between an innerspring and a latex support core in post #2 here but both can make a great support system.
Assuming that you did some good testing for PPP there is none from a quality or value perspective no and you have the added bonus and durability of a two sided mattress (as long as you flip and rotate it on a regular basis).
