It depends, too, on the method of atomization. VG has noticeably less taste, but more vapor. Most people settle on a mix from 70pg/30vg all the way to 20pg/80vg. I find 100% pg to be too harsh in a polyfill cart, but just fine in a Boge carto or CE2 clearomizer. VG, being thicker, doesn't wick well in some Ecigs.
It depends on your desire for taste, vapor, and the viscosity of the vapor. There are, by the way, people who report an incompatibility with PG as well. The key is finding your mix and the right hardware for that mix
through trial and error and reading the posts of others as they recount their experiences.
