Lidl’s low calorie version of their “Classic” variety tastes almost the same. The difference is due to the sweeteners and gives you that chewy aftertaste, but of course as with any sugar-free variation you miss out on the associated sugar rush and crash. I quite like avoiding that but I know many people don’t, but it’s good to know that there isn’t much of a flavour difference otherwise. Due to its price and lack of sugar, this is the drink that I stock up with in bulk in my garage.
