5-hour Energy (regular) has more caffeine than Peet's brewed coffee on both counts: 200mg per 1.93 oz shot against 150mg per 8 oz cup, and about 104mg per fluid ounce against 19. 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.

The concentration gap is the striking part: 5-hour Energy (regular) packs roughly 6 times the caffeine per ounce. Sipping speed matters at that density; a 1.93 oz shot finished in minutes hits differently than the same milligrams spread over a slow cup.
Which one should you pick?
Pick Peet's brewed coffee 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.
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.
