I like Stoney Brook myself, I think the approach from the south is more scenic but both are quite nice. If you can drop a car at one end they make a nice end-to-end.
Up Stony Brook, down Carter Moriah gives you the best views IMHO. You get to look down into the Wild River valley, up toward the Moriah summit on the way up. I guess just like the Stony Brook approach.
I guess what you are hearing is that both ways are excellent (the Rattle River approach is pretty sweet too!)
