It is very "refreshing" to find a drink is the US market made with sugar, rather than corn syrup. As an American not familiar with Tamarind, I enjoyed the new flavor--a bit tart, though with just the right amount of sweetness from the sugar.
It has a nice pulp content and a pretty fresh tamarindo taste to it. Other tamarindo beverages I've tried are Jumex and Goya (and I think maybe Jarittos has one?). This ranks well among them and is quite refreshing. The tamarindo itself as a fruit I would not rank high among my favorite fruits.
