My last order was from Vapers Tek. I wanted to check out their nic and some Inawera flavors, and I was very pleased with both. My next order will probably be from Bull City Vapor. I usually wait until I need nic as well as flavors and it's my understanding that Bull City gets their nic from Vapers Tek, plus they seem to have a bigger selection of flavors.
Here is a thread on Vapers Tek nic in case you haven't seen it.

Of the ry4 flavors I've tried, the only ry4 that I like other than my own is the ry4d from TFA. Unfortunately, my last order of it was very weak. Bad batch I guess. For my own recipes I like vanilla swirl, caramel candy, and almond (all TFA) for mixing with my tobacco flavors.
The only brown sugar that I've tried is the TFA. I'm happy with it and reorder when I run out.
I've never tried any butter rum so I'm no help there.
Good luck and happy vaping.
