I like TaB best; but Diet Vanilla Pepsi (DVP) is just about as good. At least DVP is available in 12-packs and 2-L -- which go on sale often, whereas TaB is only offered in 6-packs of 12-oz cans -- which never go on sale around here and cost more than twice as much. The DVP is the first PepsiCo product that tastes better than it's Coca Cola Co. counterpart.
