Monster or Redbull

I don't drink either of the mentioned choices. I've always been meaning to try at least one of the drinks but have never gotten around to purchasing one at a store (mainly because I have such a short attention span). Does anyone have any flavors they'd recommend?

I prefer monster but I once drank redbull because i was thirsty and it was a hot day

Redbull because christ mountain dew tastes like pure unfiltered ass
