I have a Kabuki clone tank, with a second one on the way. Previously I was okay with using Nautilus Mini tanks, which are certainly okay for MTL style vaping, but far from perfect. The Kabuki isn't perfect either, but it is a more satisfying MTL vape all around. It has better flavor, improved (nice and dense) vapor production, holds a bit more juice (though it uses a bit more too), and is also lower profile than a Nautilus Mini - without being too heavy or fat. I can run a bit more power through the same Aspire Nautilus BVC heads the Kabuki uses without quickly shortening the coil head's life - as would more often than not be the case when using those same heads in a Nautilus Mini. It isn't that much more fiddly in comparison to how much you have to fiddle with a Nautilus, which isn't all that fiddly anyway. Some people just leave the Kabuki AFC screw out, so as not to have to fiddle with it at all. I haven't gone that far, as I like a reasonably tight draw, but I'll try it out on my next Kabuki clone tank when it comes in. Usually I just use a bit of thread lock on the Kabuki's two (2) adjustable screws (one for AFC, and one for the adjustable 510 connection), so they stay where I want them, which has worked perfectly fine.
I've tried an Innokin Prism T22 MTL tank, which I found to be way too warm, and I did not like the proprietary drip tip design, or lack of any AFC. The new Nautilus X tank sounds like it has some potential, though it is also supposedly extra warm, and unfortunately its AFC arrangement requires a lot of regular fiddling - due to a design that could have been better thought out. So, for now anyway, I'm very good with the Kabuki clone's performance and day-to-day usability. My next few tanks will probably be MTL RTAs, which I'm having a hard time making up my mind on. I like the Kayfun Mini V3 (and maybe the Kayfun V5?), but also the Mini Goblin V2, Hurricane, Pico, etc. I might just play it safe, and cheap, by getting a Kayfun Mini V3 clone. I can only use a no larger than 20mm or so tank anyway with my current vape gear, so that is pretty limiting. Most MTL RTAs will be big bigger around than that, so I think the V5, Hurricane, and some others are not options.
