What is the difference between VG and PG E-Liquids?

[WHISPER]

Can anyone tell me what the difference is between VG and PG e-liquids please?

My limited experience with PG tells me that VG seems to make better vapor. At least, it seems I get more vapor out of VG. It also doesn't give me a dry throat. I order nothing but VG now.

PG better throat hit, VG more vapor. Some VG juices have plenty of TH (Vermont Vapor, probably others). VG=easier on the throat, so if you've been vaping PG all day and have a dry throat, switching to VG is a welcome relief.
