The last one on the right is the RBA section where you can build your own coil if you choose the other 2 are pre-built by factory... now people sell the coils as pre built coils for the one on the right but you still have to install and wick.
Personally i dont ever find RDTA's to be my thing the RBA section is usually not big enough for my preferences. Hope this answers
