Not a direct comparison but I may be able to offer some help. I’ve always favoured flatter saddles. Specialized Alias/Toupe, I’m also one of only 3 people in the world that liked the Bel Air 2.0.
I run the SM Pro on both mountain bikes. I favour more technical terrain so there’s more moving about.
My gravel bike has the SR Allroad Core as I’m sat down more and there’s less squish (tyres or suspension) than the other bikes.
It’s a noticeably more absorbent saddle than the SM but I have no desire to switch them out for Core versions.
James Thomas (bikefitjames) has some interesting thoughts on saddle width that make sense so I’ve always picked the narrower ones and been fine, despite what some ass-ometers might suggest.
