I will agree that KBV has the most consistently great flavors of just about anyone. My only concern with them is that their juices tend to be pretty thick and not provide as much TH, even at 70% PG, so I lean away from them for work/outside the house vapes. At home though, especially at night, I hit my KBV juices pretty hard.
Based on some recent tastings of 10 of their flavors, I would also add Vapor Station to the discussion.
