I like vg juice for the same reasons starzz mentioned.
One con I've found is the wicks on my clearomizers get gunked up pretty fast. Within a couple of days, actually. When they do, I don't get much of a flavor hit.
To get around this, I just have multiple clearomizers and replacement heads. That way, I can just pop a fresh head on there while I clean the gunky ones. I've taken to cleaning my stuff in an ultrasonic cleaner but I find my wicks can still be a bit gunky after several cycles. I like to soak them for a few hours in vodka, then rinse them really well. Vaping from a wick that is still damp with water is unpleasant. So having lots of extras lets me make sure I always have a clean, dry one on hand.
