It's a draw.
Both the Titan and the NJoy produce coherent smoke rings.
I like smoke rings. For me it's a big part of the relaxation. It took me some time to learn to do it and it's nice to see that Electrofag allows it too.
Smoke rings are an indoor thing unless the air outside is really still. They don't work in a gale cutting across a maliciously-designed smoking 'shelter'.
Both the Electrofags I've tried produce good rings. That part works.
