I absolutely love the PG Cafe Mocha (juice - carts taste a little funky, but I order them and juice them up)
I tried the VG since the PG is currently out of stockhere's my opinion:
taste - same basic taste, just much "lighter" (might have more taste with a higher nic)
super thick juice, it feels like trying to suck a Frosty through a super slim straw (Wendy's extremely thick chocolate milkshake - best to eat with a spoon incase you don't have Wendy's in your area)
VG cartos work better for me on manual batts. It has a harder draw on automatics. At least with my batts.
