well the Spike Shooter gets two thumbs up from me. First off the taste is great, as is noted in the product thread. . its kinda like a cherry/raspberry type flavor. I might be off, but the bottom line is that it tastes awesome. Second thing is that the effects are very similar to the Spike tablets; which I have to add that I'm also a fan of. I drank it on the way down to school this morning (6 am) and while teaching I was just full of energy. It's much better than any other "energy" drink that I have had before, and I've tried a lot of 'em.
hope that helps! I can't really say that one is better than the other they both definitely do the trick for me. . . I just dont know how to use one vs. the other.
