I concur, I was loving the heck out of my Nautilus tanks. (I have 3). Then Yesterday I decided to try my first build on a Taifun GT Clone I had purchased. HOLY MAN! What a difference in the experience. Flavor is probably double, throat hit is intense, and nicotine absorption is also higher. I picked the Taifun up for alot less $$ than the Nautilus. The only caveat is it shipped from China, so it took like 3 - 4 weeks to get here.
Also to answer your original question, Yes the Nautilus handles vg juices just fine. One of my tanks has Alpha Vapes Sweet Tooth in it, which I believe is a MaxVG juice.
