cranberry: tastes exactly like carbonated cough syrup
blueberry: not terrible, maybe the best of the bunch but the flavor is too strong for my tastes
'lime': i think they mislabeled the cans that were supposed to say 'poison' because it tastes like goddamn poison
summer: it is OK, on par with the blueberry but again the extra juice(?) flavor is still too strong, or maybe it doesn't mix right with the Red Bull flavor
original: still the best, the sugarfree is very good too. total zero is if you just want the energy and don't care about taste
Monster Import: you should just get this instead, ****'s delicious. It's basically Monster with more sugar and flavor syrup in it, but you are already drinking an energy drink so who cares, right?
