I'm a huge Boba's fan. It was my ADV for several weeks then I got low. Of course I ordered more, but I also ordered some juice that's been compared to it.
I have some Grumpy's that I really like, but I can't stealth vape it at work. It puts out an odor that others non-vapers and non-smokers find offensive I guess. So I use that one at home in the evening, or if I'm out someplace I can vape. Just not at work.
I just got 30ml of El Kamino last week and I chain vaped it for 3 days. It's awesome. I like it as much as Boba's but I wouldn't say it's necessarily better.
Those are my main three and any could be an ADV for me. I have some Halo that is ok, but for me, there is just something that doesn't sit well. An aftertaste I can't quite put my finger on, but it doesn't make it unvapable, I just won't use it if I have my main 3 available.
I've heard great things about Deadly Sin, so I think that may be the next one I try.
