I'll go ahead and highly recommend the Protank II
I don't have one myself (yet) but I do use a Protank I and like most users I was pretty impressed straight out of the box. The Protank CAN get a bit leaky, but it's a well known issue with vaccum pressure and the easiest way to remedy is by keeping the juice topped off whenever possible. Once it gets below half a tank you'll start getting some leaking.
I've heard the Protank II doesn't have an issue with leaking but I haven't tried it myself so I can't attest. One thing I do is when the juice starts getting to half, I'll angle it up so gravity isn't forcing more juice onto the coil when I puff. It's a bit annoying and might look odd, but it works if you don't have time to fill it up.
If that doesn't sound like your cup of tea, maybe something like the iClear 30 would suit your needs better. Ironically enough, I've heard it leaks if you overfill it.
Another option would be to skip the wicks altogether and go for a Carto Tank setup. They're well known for not needing to be refilled often AT ALL, typically durable, and probably IMO one of the better systems you can use for simple, on-the-go vaping with minimal mess.
