welllll.....
Since "taste" is quite subjective, its difficult to give an answer when one persons preference will most likely differ from another's.
So here's mine:
I prefer VG !! And I choose this because "to me" I enjoy the taste which "I" feel sweeter and less of a chemical taste that I get from PG.
I also prefer VG for the thicker consistency that can be thinned to preference, rather than PG with is very thin.
I (as many others have) find VG produces a thicker more impacting (felt) vapour feel for both inhale AND exhale.
PG (to some) creates a sensitivity of its use that can be anywhere from just too harsh (chest and/or
throat), to mouth blisters or sores, or general feelings of illness.
VG (to some) creates an upset stomach, feeling of thickness in their
throat, as well as other reported findings.
For the above two points I suggest reading in either the DIY
juice forum, or the medical forum (as the discussions are ongoing regarding the two).
And finally, because I prefer to use something that is derived for a vegetable source than a chemical compound.
That's my thoughts on it, and others may differ, but it really ends up boiling down to your own experimenting to find which YOU prefer.
