Monster Rehab (Tea + Lemonade) carries more total caffeine per serving (160mg per 15.5 oz can vs 95mg per 8 oz cup), but ounce for ounce brewed coffee is actually the stronger drink at about 12mg per fluid ounce against 10. Which one "has more caffeine" depends on whether you measure the container or the concentration.
These are different categories of drink, which changes how the caffeine arrives. Energy drinks and sodas list an exact number because caffeine is a measured additive; brewed drinks vary with the beans and the brew, so their figures are compiled averages. The numbers here are the standard published values for each.

Which one should you pick?
Pick brewed coffee when you want the lighter dose or a slower ramp, and Monster Rehab (Tea + Lemonade) 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.
