I just started vaping 100% VG juice recently. The first night the TH was super harsh. I was surprised because I thought with no PG it would be wimpy with no TH at all. Wrong! This stuff packs a wallop. I got used to the different throat/mouth feel in just a few days though. Flavor-wise, the stuff I bought was really full-bodied and tasty! It convinced me that you don't need PG if the juice maker knows how to craft a good juice.
I hear what you say. VG for clouds!
But, for flavour - well, ymmv.
I guess they stuffed a load of fruit in your juice!
