I have used both the Tank and cartos. My opinion is that there seems to be less of a TH and the vapor is cooler. I can attribute that to the fact that the Tank allows for more cooling of the vapor due to the size and shape of the system and less contact with material that will retain heat. Mind you, I use 808D-1 cartos and the vapor seem to get to my mouth rather warm in comparison with the tanks. The Tank system has many features that I do like and that includes the fact that I am able to easily fill the tank, see when it needs re-filling, and change flavors just by changng the tank. Pop off, pop on, done grashopper. The taste does seem to me to be different, not necessarily better or worse, weaker or stronger, just different. I still use both fairly consistently and each has their own pros and cons. The biggest drawback to the tank, for me, is the price for the tank-o-mizer and when it is blown there is no rebuilding. I took one apart that died on me after only a week to see if ther is any real way to work on/repair them. There is not, at least with the Inferno Tank-o-Mizer. Good luck and go for the tank.
