To some degree, the different materials depend upon your intended use. Rubber and cork have an obvious advantage over bare metal in many circumstances because it can be cinched down to use pressure to hold the plate next to the camera/lens/whatever. If you'll be taking the plate on/off in the cold, the rubber may last longer; cork will tend to dry out and crack more quickly -- though this would only be a notable concern if you're taking the plate on/off in very cold weather. The bare metal plates you link to only have an advantage in the life of the product, in that there's nothing to dry out and crack over any length of time. The downfall of any of these options is that you must tighten the plate adequately to eliminate any wiggle (which often means applying a good amount of torque).

Of course, if you are considering the Arca-Swiss quick release system you should really look at the custom, form-fitting plates from Really Right Stuff and Kirk Photo. Both companies make plates that follow the exact contours of the camera/lens/whatever to precisely and tightly fit -- so there is no opportunity for any wiggle movement whatsoever.
