What energy drink has the best effect on you?

For me C4 seems to genuinely give me good energy that keeps me awake and feeling good for a few hours. I love rockstar and they taste amazing, but I feel like I drink them and then crash like 2-3 hours later. Same with basically every other energy drink, I don’t really pay attention to the caffeine content of drink because I mainly like the taste, but C4 seems to be best at 200 mg. What’s your guys’ opinions?
