The Boge 2.0 has a heating element that runs vertically up through the filler material that holds your e-liquid. Many people like them because you can pry the soft cap off the mouth end and fill, and you can see your e-liquid absorbed by the filler.
On the other hand, I like and use the Joye 510 carto. The heating element is in a coil below the filler material, on the battery end of the carto. I fill a new carto with about 35 drops of my e-liquid, and refill with about 12 drops thereafter. The Joye carto is just a little longer than the Boge, so it protrudes from the cone by about an inch (vs. about a 1/2-inch for the Boge).
Either carto will work with the eGO batteries. (I use the regular 650mah batteries.) If your original kit was the eGO-T, then you may want to also purchase an eGO cone when you switch to cartos. IMO, the cone makes the eGO nicer lokking, but it also makes the draw just a little stiffer (which I like), and it also keeps juice off my hands, in the event of samll amounts of leakage.
Give cartos a try. I tried the eGO-T and it wasn't for me.
