3D Energy has more caffeine than Monster: 200mg vs 160mg in the same 16 oz can. That is a 40mg gap, and since the cans match, the per-serving number is the whole story.

Which one should you pick?
Pick Monster when you want the lighter dose or a slower ramp, and 3D Energy 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.
