The flavor I tried is Strawberry Kiwi, which is so new that I couldn't find a picture of it. I got it in an eight-pack on sale at Wal-Mart. Somehow, it has taken me three days to finish one 20 oz. bottle, but that's because I haven't been training strenuously yet.
The taste is very light and clean, hence the word "rain." It certainly causes less bad breath than the Gatorade I am used to (Lemon-Lime), and it's a lot cooler-looking as well. The nutritional content is the same (50 calories per 8 oz.).
I wouldn't say that this trounces the "regular" Gatorade until a cheap powder form is made. Oh, and I still like Endurance Formula the most.
