5-hour Energy (regular) has more caffeine than Starbucks bottled Frappuccino (Mocha) on both counts: 200mg per 1.93 oz shot against 105mg per 13.7 oz bottle, and about 104mg per fluid ounce against 8. The serving sizes differ, so the table below shows both ways of counting.
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 Starbucks bottled Frappuccino (Mocha) when you want the lighter dose or a slower ramp, and 5-hour Energy (regular) 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.
