Wow, that is really a subjective question. So far, I've found that it depends on the delivery system I am using. I am also very new to
vaping, so you might hear differently from many others. From what I've read though, PG tends to be both more flavorful and delivers a more potent throat hit than VG. VG delivers more of that vaper cloud than PG. My favorite
juice right now is a 50/50 delivered from an Atty (limited gear at the moment) I tend to use 70/30 in my single-punched carto
tank. I'd like to get into something like on AGA-T+ and be able to run the 50/50 through that. Ultimately though, it boils down to user preference. There are folks that are PG sensitive and will only use 100%vg. There are also folks who simply prefer 100%vg over anything else. So really you'll have to determine what flavor and vg/pg combo you like most and that will be the best for you.
