I'm not an expert, but I was looking at a few hubs the other day and I got the impression that the difference between "standard" and "premium" is the construction of the hub itself. The standard hubs use a plastic rotation knob for selection, the premium uses a metal knob, often with a stainless steel or brass plating. The websites seemed to indicate that the locking mechanism was nearly identical, and thus both the standard and premium have a lifetime warrenty.

Maybe there is something better about the premium, like an extra seal or something to give it more longevity, but I didn't get the impression there was a tremendous strength difference between the two.

I could easily be wrong, however.
