I used the N2 to quit and I liked it a fair bit. I do use the Nautilus coils though, although in different tanks nowadays. I liked the Nicolas Vapefly too, at the time I thought it was super cloudy, LOL but nowadays it's in the realm of normal. You can definitely close down the N2 more.
I think it gets better flavor (the N2) than some of the older models but I am sure glad it was around for quitting, and I still love that coil (my favorite is the 1.6 it's a nice balance between the 1.8 and the 0.7) but I use it in Kabuki tanks, and also an Ijoy elf which I also think are nice tanks, and they fix most of the N2 problems (less of a cage, so less metal to act as a heat sink, better flavor, true 2 ml capacity and much easier topfill system as well as more flavor (I'm pretty sure). I think they're getting hard to find, and they also have proprietary coils, although I think the Nautilus coils are better.
I also must say you aren't going to beat the Kabuki for flavor with those coils, but it's a bottom fill system, and 3 ml not 2, but I'm glad I bought a couple, even though they were one of my heart stopping vape item purchases, honestly, but I use them all the time.
If you want something even a bit more robust, any Joytech CLR accepting tanks can be nice with the 1.0 coil (which can be rewicked and rebuilt fairly easily, well, something like an ego mega v2 or a Tron S or an Oddessy totally wicked tank, you might enjoy those coils. I (personally) have a hard time keeping those tanks alive, but I seem to be the only person having that trouble and granted I'm hard on my gear, honestly, but if I get an "ohms not reading" message one more time... LOL. I will say the Oddessy tank is the only one that doesn't give me that message although to be fair, it also travels from my vape stand to my mouth and nowhere else. I have a couple of the 2 ml ego one original tanks and I will say the flavor is even BETTER (mainly, because I made a stern commitment to NOT buy any more of those tanks) although the refilling frequency and process on them is a bit grim although they are holding up fine so far....
I think the COILS get more life than my tanks do, but I will for SURE say, I seem to be the only person having this issue, IDK what it is with me and those tanks, although I am betting it's a "me" problem, I'm also mentioning it because if you like the Nicolas Vapefly, I guess I'd compare the 1.0 CLR coil to THAT system on steroids as far as vape density and flavor, and I think you might like it.
Best of luck,
