Between the Brookes Low-Can Passion Fruit and Orange, I definitely choose the Orange!
When you have the well-known Oros man on your packaging, you cannot compromise on taste or fall short because there is some sort of expectation. I was not disappointed.
All-in-all, I prefer the orange. It wasn't as sweet as the Passion Fruit flavour and the fact that I can enjoy it without the possible sugar craving creeping up on me means that this lasts a lot longer than other drinks such as sodas.
