There is a group of juices that I consider to all live in a general taste vicinity, Boba's being somewhere in the middle. There are certainly differences in the individual flavor components but overall they give me the same flavor aura (for lack of a better term). I have these all in regular rotation:
Boba's: I do find this to have more pointed tobacco notes versus the others that are more sweet/dessert-ish.
NLV Bounty Hunter: Again, some identifiable differences but I regularly interchange these. They finally have it at litecigs for credit card purchase.
Copper Creek House Blend- they describe this as a coffee, but I still consider it living among these other juices, just more dessert-like.
BWB Malty Toffee- still on the more sweet side but as the name implies picks up on the malty component that i taste in Boba's
Goodjuice Vita Bella- I just turned onto this a few months back and have to say it's become my favorite in this group. The tobacco is really present but well-balanced with the other flavor goodness.
Ahlusion Smooth Criminal- This is getting farther away from Boba's but if you're looking for a sweet tobacco then you might like this. I'm vaping it right now so figured I'd include it
I get more cream/vanilla with a slight spice like cinnamon, but well-balanced with the tobacco. Super nice.
edit: doh i forgot about your 100% VG need so some of these may not be available all VG.
