My personal pick is Livewire, but let's get a general consensus from KF.
DewShine before the discontinuation. Currently, 2020 VooDew, fuck what you heard. But if we're talking year round flavors, Baja is hard to beat.
Mountain Dew Black Label.
Besides the dark, velvety smooth, berry-licious flavor?!I had that. I'd prefer it to a regular dew but idk, I don't remember it having any especially memorable traits.
