Never ran either but I'll be running TNE in oil in January. From what I've heard the oil is supposed to be painless. Not so much with water lol. Apparently water is absorbed slightly faster, but like I said I've never used either yet.
I like oil the best smooth as shit! Takes about an hour to hit But when it does it, it hits hard. Love it. Water is very painful and the guiacol smells like shit.
