DBV also takes a hair more care during use, due to the horizontal heater angle and ground glass connection (the same would be true for the SSV with the ground glass HF setup, but not the standard).
The same is not true for the SSV. The ground glass SSV does retain the signature SSV downward angle. It does not require the same amount of extra care as the DBV when inserting/removing the wand.
