They look similar, but obviously not the same. One has a silicone surface while the other has a hard surface. I can see the spec differences, too. In actual use, the vibration notwithstanding, how close are they? That is to say, if one were to chose just one, wouldn't the added vibration be a benefit? Or, are they different enough where they will feel vastly different? Please share your knowledge and experience. Noob here. Thanks!
