I have had sketchy results with clearos too. The reason for the burnt taste, at least from what I've discovered is the fact that the resistance of the clearo is not enough for your battery. Most batteries, such as the Egos, are 3.7V. With a 3.7V battery, you typically need to be over about 2.2 Ohm of resistance in order to avoid getting a burnt taste, but less than 3.5 Ohm. Since most clearos are only 1.5 Ohm, that may be the source of some of your frustration.
I personally love the DCT tank. They come with a 1.5 Ohm dual coil cartomizer, for a total of around 3.0 Ohms of resistance. This gives great vapor and the tanks hold 3ml or 6ml of juice depending on the tank you get. The best DCT tanks that I've found have been at Vapingzone.com.
I should clarify. Im getting zero burnt taste from clearo's. So far they are my favorite. The issue is. (and this didnt happen until i got juice from madvapes.com) when im vaping them. They get juice in the air tube. I'm getting burnt taste from the CE2s that i just got from gotvapes.com today. Even after letting them sit i cant vape them for more than 2 hits before they get burnt taste. My vivi novas arent getting burnt either. they just constantly get juice in the air tube when vaping.
Thank you guys for all of your help so far.
