The numbers here are the standard published values for each.

Which one should you pick?
Pick Red Bull when you want the lighter dose or a slower ramp, and Starbucks Nitro Cold Brew 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.
