Blu Cigs -- Helped the transition from analogs, but didn't help when a major craving came up
Ego T -- Awesome! Loved it. Aside from the leaking, this thing really helped out during the worst of cravings
Ego C -- Fixed 99% of the leaking issues. Not to mention cheaper and easier to change atomizers.
Ego Twist -- My first step into VV. Down side - The little Ego C atomizers couldn't keep up.
ProVari V2 -- Holy crap I love this thing. Haven't looked back since! With a tank and carto setup and newly found flavors of juice I am in Heaven. It took me a long time to drop the cash on this thing, but, Wow! Very solid and well made. Never tried any of the other companies big tube mods so I'm not going to judge. To each their own and no point in getting into a battle of VV mods. There are other Threads about that.
No matter what you decide to use...in the end, you are off of analogs. That's what really matters!!
