The way I understand it, PG is actually a better carrier for flavorants, so higher PG will taste better. VG is thicker and produces much more vapor, but the flavors will taste more muted. Most "Max VG" eliquids will still be some ratio of PG and VG, unless you go with liquids that are sometimes sold as "Organic", etc, which may be 100% VG.
I believe I may have a slight allergy to PG because if I vape too much 50/50 juice it will break my face out. For that reason, I've started dripping higher VG blends. You should try the Epiclouds line by Namberjuice. All of those flavors are pretty amazing.
