You can't really make a direct comparison of various Vibram soles. I have used a number of them, from the heavy duty lug soles in the 70s to recent Merrells.
My current pair of Merrells (Phaser Peak) have very grippy soles, so I was not expecting them to last a long time. I got them last spring, and have used them on some hikes in the Sierras - a half dozen two day hard rocky trips out of Mineral King, two trips over Mt Whitney (a 70-mile route from Horse Corral and a 45 mile trip out of Horseshoe Meadow), and an 82 mile loop in Kings Canyon NP, as well as a number of easier hikes. If you have much experience in the high Sierra, you know that it can get pretty rocky, especially when summiting (the summits I have done out of Mineral King have involved a lot of boulder hopping). These boots have been very comfortable, and I have been surprised at how well they are wearing - they have very little visible wear on the tread.
