Tue Rolls is a bit wider and flatter at the back half of the saddle than the Turbo. The padding is also a bit thinner on it.
I find the Turbo more comfortable, but it's maybe because of my narrowish sit bone spacing. I also developed an iron butt from years of riding the Concor Supercorsa saddle. Once you get used to Concors, which some considered as an "ass hatchet" saddle because of it's narrowness and thin padding, you can ride pretty much sny narrow saddle without sny problems.
