I totally feel you I have ordered from Johnson creek, Nhaler, DIY Flavorshack, My freedom smokes, I vape, strictly e-juice, Keemer, Ms. T, American e-liquid store, Rath, and I just placed my order with Tasty Vapor. I will would say 10% of the juice was gross, 50% was ok, 20% was good and 20% was amazing. I just sold the stuff that I thought was gross or just ok. I use the amazing stuff as a treat and vape the good stuff most of the time.
Am I picky? Yes, but I want the best experience possible because I never want an analog to start to look tempting. So far everything from Ms.T has been in the good to amazing category, American e-liquid store butter rum and english toffee were amazing. I have not received my TV order yet but so far those two vendors have been the best out of the 10 I have tried.
