I am still pretty new to
vaping, but i have bought around 60 bottles of juice, and probably tried another 40-50 flavors between sampling a bunch at Beeliquid's brick and mortar in Taos, NM, from my brothers stash, and my mothers stash.
Vendors i have tried:
Beeliquid
Heather's heavenly vapes
Virgin Vapors
Alien Visions
NicQuid
Volt
Backwoods Brew
Fuzion Vapors
j u i c y vapor
Nicoticket
Captivape
Mom and Pops
All of them had flavors i liked, flavors i loved, and flavors i hated. I wish it was as easy as asking this community for a couple good flavors, but everyones tastes are different. I will give you my suggestions, but they don't mean anything until you actually try them for yourself. Not only that, but your preferences will change over time. There are flavors you will never think you will like until you try them, and they will open up even more possibilities for finding juices you will like. Don't limit yourself looking for the perfect pina colada flavor, because even if you find it, you will likely get sick of it if it is all you vape.
The vendor with the highest percentage of flavors i will reorder was Beeliquid. I will be reording their Zombee, RY4.1, MellowMax, Minion #2, tobacco #21, french vanilla, and dr. pepper. All great, mixed to order, have gotten better now that they steeped, and i vape them all regularly.
The most flavorful vendor i have tried has been Zeus Juice. If you are looking for a flavor punch to the mouth without having to order any extra flavor shots and end up with something too purfumey, than check them out. Their Zeus juice, and Tiger's blood sound right up your alley, but again, i would branch out to some stuff you haven't tried.
The overall best flavors i have tried have come from Alien Visions, and Nicoticket. Boba's Bounty, Gorilla Juice, and Hype from AVE, are probably all in my top 5, and nicotickets creme brulee as well. I would bet you would like Nicotickets Betelgeuce. People rave about it. I have some, but am letting it steep a little longer because right now it just tastes like muddled fruit (not in a bad way, in a "this need to steep" kind of way).
