i've got a vaporizer. It gets me very high quickly. One additional reason is that even more so than a bong it is a huge rush of THC to the system.

oh and about the whole coughing thing Shai: I cough much more easily off a vaporizer than smoking. My vap bong is very intense on the lungs, and people easily throw up or have huge coughing fits off trying to hit it like a bong. Vaporizers really irritate the throat a lot in my experience using them. I have used the Voodoo and the Got Vape vap gun/ bong kit. the latter one defeats the prior by a lot, and the price is like 50-60 more.
