I've been ready to retire my Nautilus (with the cage tank) so many times, but for me, it's still the best overall for MTL, and alongside flavour monsters like the Aspire Cleito and Uwell Crown, my Nautilus still gets vaped every day. Sometimes I just want a nice ciggie-like MTL and for me, the Nautilus is still the best for that.
I got a Triton Mini and it's a good tank, but I just couldn't quite get the airflow set up that I love with the Nautilus. The great thing is though that I now buy the Triton Mini Clapton coils (which fit the Nautilus), and they work exceptionally in the Nauty.
I do build coils, but sometimes I just want to slap a coil head in, fill her up and be done.
