I can't compare this to the FF2, because I never owned one. What I can say is that I'm happy with this Firefly. I've had no trouble with draw resistance. I also use a Milaana and a Splinter, so I'm used to modulating my intake. The resistance on the Firefly seems comparable to those vapes. The flavor and coolness of the vapor is as good as my Splinter, maybe even a bit better. I've had no battery trouble whatsoever and I enjoy using it. I would recommend the FF2+ wholeheartedly.
