Gatorade vs Powerade
The tastes are very similar, however because Powerade has a higher sugar content and lower sodium content than Gatorade, it is considered by many to have a slightly sweeter taste. Powerade and Gatorade have about the same amount of flavors now.
 Sugar Type
Gatorade uses normal glucose where as Powerade uses a different type of glucose, polymers. Studies have shown that polymers such as maltodextrin are absorbed into the body fast. Although Gatorade has a high level of sodium content (almost twice that of Powerade), I am more interested in the sugar level when in the middle of a run as it is much easer to get sodium from day to day foods than it is when a slightly higher sugar spike is needed (about 6gms Gatorade to Powerade’s 8gms).— Tiger Woods, and Kanye West , Yourhub.com: Gatorade vs. Powerade
Powerade contains high fructose corn syrup, a heavily processed corn-based sweetener that has recently begun to gain controversial attention for its supposed health dangers. Gatorade is sweetened with sucrose and dextrose.
 Sodium Replenishment
The sodium content of Gatorade is about 450 milligrams per liter; for Powerade, it is 225 mg/L. Thus Gatorade does a somewhat better job of replacing the sodium lost in sweat. The sodium content of Powerade Ion4 Advanced Electrolyte System, however, is just under 425 mg/L.
Viewed scientifically, the differences between Gatorade and Powerade are small, with neither beverage appearing clearly superior to the other. I personally prefer Gatorade, since it replaces sodium losses more effectively than Powerade does. However, this may not be an important consideration except in very long runs in which several liters of sweat are secreted.— Greg Crowther , Gatorade vs. Powerade: battle of the beverages
