IMHO any grease with a fiberous content to support bearing load or any grease with a thicker consistancy (read automotive grease for the above) will have more bearing drag than a lower consistancy teflon impregnated one. As stated above, the load on a bicycle hub bearing is nowhere near as high as that on an automobile so why have the thicker stuff in there? You may find that the thinner greases need to be replenished more often but the question was about performance.
