Taste is just too subjective for there to be a consensus on who has THE best tasting juice. For example, DantesInferno just said Bobas Bounty is "plain and simple goodness". To me it tasted like pipe tobacco, which I like to smell if somebody is smoking it, but it wasn't appealing to me as a vape. I gave mine away. So there ya go. Taste is SUBJECTIVE.
Read lots of reviews. You'll get a feel for who has good customer service or who makes customers wait 8 or more days before they even ship.
You'll just have to try the juices that sound appealing to you until you stumble across ones that YOU like.
Recently I have enjoyed the juice I received from altcig.com and ahlusion.us. Both shipped very quickly and the juices were spot on to the name and very tasty. altcig's customer service and prices are outstanding too. I'm looking forward to trying Heather's Heavenly Vapes also.
Another vaper just highly recommended vapedudes.com after they went above and beyond what was expected on a customer service issue. They also have 40% off for first time customers.
If you're on a budget you may want to consider DIY. You can save ALOT of money and if you take some time to explore the DIY juice section, you'll get help along the way.
Best wishes chasing the juice monster! LOL
