That's a tricky question. I'm in one of those phases where not a damn thing tastes really good. Been doing unflavored partially. Plus, I'm trying to steer clear of diketones etc. and also artif sweeteners such as sucralose cause I really don't think they're healthful.
So, I tried a couple of TPRs and thought they were very good, but they use sucralose, so crossed them off my list.
I liked the taste of a few MOVs but they made me cough.
AHL is said to be testing, but I haven't seen any post yet about it, but I do still like them, right now the Wildwoods and the Vecchio Blend and Cafe au Lait.
Just got some Mister E Liquid RY4 and it needs to steep a bit, but first take is it's very similar to my old fav Halo Tribeca, and it's tested clear. Also got some of their banana nut bread, but haven't tried it yet. As well as the free sample they sent of their chocolately Landslide, but haven't tried yet, but sure smells good.
