My favourite juice in the last 2 or 3 years has been fat boy. Followed wed by cush man. Both mango but very different:the former is like a very very sweet mango soda, the latter is an overripe mango juice. Both with a lot of sugar and just a bit of cooling. The sweeteners are a problem if you don't use rebuildables as they gunk up your coil very quickly.
Another couple I like are slow blow and the bronze tobacco
