Yes, VG = Vapor and PG = Flavor but neither is exclusive. PG will still create vapor and VG can carry decent flavor
Obviously cloud chasers want 100% VG
That slight extra throat hit from PG is more of a dry sensation than a harsh smoke-type throat hit. Vaping juice with PG over 20% always leaves my throat raw and dry almost as if I'd been smoking. Some of us (myself included) are extra sensitive to the effects of PG. Unfortunately PG carries flavor more cleanly and for this reason most flavoring manufacturers produce most of their products in this base since they are aiming for flavor, not vapability, as their main market is candies and foods.
Then many juice makers want their juices to taste their best so they're reluctant to mix them VG heavy as they have to add more flavoring. Usually too much flavor is worse than not enough. This is why I started making my own juice a couple years ago. I know exactly how much PG I'm getting and try to keep it as close to 5-15% as possible. The natural sweetness of VG is a bonus for many flavors of course but now everyone calls me for juice especially as drippers, high wattages, and subohm builds gain popularity. Something like an Arctic tank can cost you more than smoking if you're buying premium juice.
