Well, the rib adds weight to both over the standard barrel.
The grip frame is a matter of feel to an individual. The Bisley grip is pretty popular, so comparing the two is probably a good idea.
It's a really nice .44 Magnum to shoot in either grip style. The weight takes the bite out of the meanest .44 Magnum loads. It will never be a .38 Special, but compared to the shorter SBH's, it's a much easier gun to manage with heavy loads.
