I'm running a Protank 1, Two Kanger T3S, and an Aga-T2. The Aga is for home use, when I'm on the go, I use the Protank or the T3S.
I use my Protank more often these days, since I'm a bit weary of Tank cracking e juices, but I *think* non of my juices fit that category since I'm not partial to any of those tank cracking flavors (cinnamon, citrus, etc.).
The most versatile, handy, and reliable of them all is the T3S. The Aga-T2 is fun and hits hard, but it's not something I wanna carry with me when I'm out and about...
The Protank 1 is good, but ever since I switched to using T3S coils, there's some slight leakage through the 510 threading... I'm looking into that at the moment, since I rather be using Protank than my T3S simply because it's borosilicate and SS combo and bottom feeder so the tank is essentially sealed (except for that leaking issue I'm dealing with of course

)
