I reckon it depends on what sort of atty you are putting your juice in, some will find it hard to wick with thicker juices. Doesn't bother me either way as I am 50/50 pg/vg, and if a device doesn't want to work with that, f*** it!
I saw this thread earlier but couldn't remember if it was deionised or distilled. I knew one was good and one was ungood but buggered if I knew which. Not that it matters cos I use Vodka anyway lol
