mmm, I'm gonna go curveball and recommend the Nautilus X
... simply because you don't like the nautilus 2, most of my tanks I rate for MTL use the same coils as the nautilus 2, Nautilus, Nautilus 2, Kabuki, Vika Fantasy... they all vape very similar to what you have and don't like.
The nautilus X is pretty different, my best mate uses it exclusively, I gave him both of mine because he liked it so much. .. he vapes 18mg liquid and uses the 1.8ohm coils and is more than happy.... so that might work for you too.
