After trying about 10 different Gamersupps flavors (all of which were pretty good), this one is easily my favorite! I'm glad that I went with the caffeine free version because I can't stop drinking it. And honestly, the caffeine free version still gives you a bit of energy from their nootropics blend, so it's still well worth it.
I originally was trying to find the best lime flavor, and I tried a few different flavors that included lime in their description (Blo'hole blast and Guacamole gamer fart). This one definitely tastes the most like lime and has a bit more punch than the others, but it is still not quite as strong as something like a limeade. The added heat at the end is perfect for it and reminds me of the Flamin' Hot Mtn Dew flavor. Some Gamersupps flavors have a bit of a bitter aftertaste, which I notice with most sugar-free drinks, and I think the heat at the end of this one really helps mask that bitterness.
Overall, I think this one is the best choice for someone looking for a smooth, citrus drink and likes/doesn't mind the heat.
