I’m going to disagree here after trying multiple flavors of both. The flavoring alone has kept Xyience in the top spot for me. The extra caffeine in Bang isn’t worth the cost and taste. The lower caffeine is actually just fine for a nice wake up.
And if you are going to compare the trash from Monster / Red Bull / Rockstar - make sure you compare apples to apples. All of their calorie free versions taste like trash or you can easily pick up the artificial sweetener.
