I would try some small samples of various juices. Try one in 50/50 mix, one in 70/30, one in 30/70 and one in 100%VG. See how you get on with each one. It's all trial and error. What someone else likes you may hate. Sorry, but that's just the way it is.
Personally, I prefer thinner juices, so I usually go for a 70/30 PG/VG mix. But there are a couple of juices that I bought initially in a 50/50 mix and they work for me like that, so that's the way I order them.
