I recently switched over to sensitive toothpaste (specifically Colgate) because I've been using Opalescence quite a bit lately, but other than that I can't really say I've ever noticed any difference among the probably 20 or 30 different brands I've used over the years. I think it really comes down to just finding one that you prefer the taste of most -- it's fairly reasonable to assume that the whole "whitening toothpaste" concept is largely a consumer marketing tactic.
