I have never used a T2, so I will admit my ignorance right off the bat. I do use the MT3S clearomizers and I like them. Just now, they are drawing very hard with decreased vapor production. I believe it is time to clean/change the heads. I like both the evod and the MT3S. Sometimes, and only on one battery (an eGo knock off I believe although it was sold as the authentic eGo U kit) I will get a burnt taste right after I charge the battery. I think this battery is putting out too much voltage now and then. On it's way out probably. Maybe wife's battery is doing the same thing?
Another clearo that I am having good luck with is the Vision Victory. A little bit airy compared to the MT3S but nice all the same. I block one air hole with my finger and it is great! Hold 5ml of liquid as well and has replaceable heads the same as the MT3S.
