I have REOs and the Zenesis. Both are fine choices for BB or any other VG juice. The REO is plug and play. I strongly suggest the HH357 from Avid as the atty of choice. You'll need to clean it weekly. My initial one is now in rotation, but it's been going since the last week of December. YMMV.
Then there is the Zenesis. It's a Genesis atty hybrid. You'll be making your own attys out of SS mesh--325 for VG

and kanthal wire. You can control the resistance by the number of wraps of Kanthal you use. It is an advanced user device. It is also drop dead gorgeous-at least to me. There is a learning curve. More people are learning to use them every day. It is an impressive vape once it is dialed in, but it is not always plug and play. Again YMMV.
I also have a carto tank or two, on a lowly Lava Tube. It's a back up, but I've used it for Bobas. I liked being able to dial in the vape, as Boba's has different flavor characteristics at different voltages--at least to me-- but Bobas and my Boges don't like each other for very long. They clog. My GF likes AVE Rootbeer--It will kill a carto in 2 or three days.
There are choices, each has benefits and draw backs. I prefer to get away from the Cartos, but many swear by VV and Carto tanks.
