Peace Tea carries more total caffeine per serving (23mg per 23 oz can vs 19mg per 12 oz can), but ounce for ounce Sunkist Orange is actually the stronger drink at about 2mg per fluid ounce against 1. 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 Sunkist Orange when you want the lighter dose or a slower ramp, and Peace Tea 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.
