Well RedBull is harsh-tasting and exempt of flavour. I can get the same exact flavour from store-brand energy drinks like "Blue Charge" for 75% the price off of RedBull. The size of a RedBull can in comparison to the price is just idiotic, in my opinion.
I love Monster because the cans are decently sized and only cost a quid at my local store. Great fruity flavours that are not as harsh when it comes to the "energy", so to speak.
Otherwise, you are entitled to your opinion and I will respect it. :D
