Though the ingredients don't differ (except caffeine content) In side-by-side comparison, this has a noticeably less-cloying upfront sweetness than its lower-ceffeine counterpart, making it feel slightly more balanced. The unpleasantly heavy chalkiness is still present in the latter half of the sip-- almost complelling you to take another sip-- which of course won't improve the situation. Like downing a bunch of water in an attempt to allay an undesired spiciness in your mouth. Anyway, I'm starting to feel the buzz a couple minutes into the can-- so the caffeine is definitely there and does its job well.
