I've not used a KF but my Kayfun-esque Lemo RTA puts my BVC equipped nautilus tanks to shame. I prefer to vape at higher watts with lots of airflow. The Lemo gives me that ability. I've got two more Lemos on the way and my BVC'd tanks will play an emergency/backup role. Don't get me wrong, I am a huge proponent of the BVC heads (as a lot of my past posts will confirm) but in no way can they compete with the Lemo in terms of performance. The added benefit of not dropping $2/each for replacement heads is also nice.
