I have a few of each and use both. One of the T3's had a coil/head that was a chronic leaker. I solved the problem by pulling the stem from the atomizer and adding a cheesecloth wick across the top of the existing wick. The draw improved and no more gurgling.
I've never had a problem with any of my EVOD's. They vape well and look good doing it. My only complaint about them is the small capacity.
Try a Tabac BCC from Good Prophets. A few of us have had no leak problems from that variation of the T3.
