McDonald's brewed coffee has more caffeine than Starbucks Pink Drink (grande): 145mg vs 45mg in the same 16 oz medium. That is a 100mg gap, and since the servings match, the per-serving number is the whole story.

Which one should you pick?
Pick Starbucks Pink Drink (grande) when you want the lighter dose or a slower ramp, and McDonald's brewed coffee 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.
