Bang has more caffeine than Starbucks Caffe Mocha: 300mg vs 175mg in the same 16 oz can. That is a 125mg gap, and since the cans match, the per-serving number is the whole story.

Which one should you pick?
Pick Starbucks Caffe Mocha when you want the lighter dose or a slower ramp, and Bang when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
