Here's a comparison video I did of two of the best clearomizers on the market. I don't think one is clearly better than the other. They're just really different products with different characteristics that stem from being single-coil bottom-coil vs dual-coil top-coil. A lot of it will come down to personal preference, but in general terms I prefer the construction and performance of the iClear 30, while I like the draw of the T3. The T3 also gives me a bit more flavor for sweet tastes.
