Hi and welcome to vaperland!
First, I will tell you that I am by no means a vaper veteran. I am only 3 months in. But, I can say that I have tried many set-ups from Ego-T, E-power, revolution box mod, many different cartos, dripping, carto-tanks, etc. I have come to the conclusion that the ego tank system is my favorite. Easy to fill, easy to operate, plenty of vapor and lasts all day without fiddling. My only concern was the expense of the attys. Now that the Ego-C is rolling out, it certainly will bring the Atty cost lower (5 bucks per). You can buy an Ego-T kit and upgrade later to the Ego-C as they become more available.
So, I say go for the Ego-T! I hope you find your vapor sweet spot sooner than I did.
