I am very close to jumping to a tank, but for now I am enjoying the Kanger T3. Am I wrong here, but isn't the T3 basically the same as a carto/tank? The only real difference that I see is that the T3 has a very small wick instead of filler material. It seems like the wick doesn't draw in the juice, but instead simply keeps too much from flowing in. They both have 2 holes at the bottom, are sealed in a tank surrounded by juice, and provide excellent delivery to the attie inside of a tube.
