I have the mini currently and a full size coming any day now in the mail, after using a friends. I also have the Kanger Aero Mega and the only reason I bought the Nautilus as opposed to another Aero Mega was the price. I got the full size Nautilus on sale for $21.99 with 4 coils, the sale may still be going on if you can catch it. I'm not sure if it's okay to post the vendor or if there's rules on that (if so and you're interested I'll pm it to you).
I like the Aero better for several reasons:
1). The Nautilus only has the 4 air holes, which ime is actually only 3 because I can't get any air through the smallest one. The Aero has that slider which gives much more control over air.
2). I have to use a small wrench to get the Nautilus apart for refilling and cleaning. I've had it for over a month and it's still a pain to get apart.
3). To me, it seems like the Nautilus holds juice flavor from a switch over. It takes me much more cleaning and rinsing time to change juices and not still get the old flavor, even with a new coil.
4). The glass on the Nautilus is thinner and seems easier to crack or damage (I haven't yet so that may just be my assumption based on the glass thickness). The aero comes with the backup stainless tank and the Nautilus doesn't come with any backup tank.
5). The Kanger coils are cheaper (may not be that way for long). I have been dry burning both type coils and the Nautilus coils are better imo so this may be a moot point.
With all that said, I did buy another Nautilus tank so it's not been THAT bad for me for I'll be buying another couple Aero tanks in the future.
Even though you're asking relating to a Provari, I thought I'd share my thoughts anyways since you're a Kanger fan. Please let me know if you're interested in that sale, it's the best price I could find after lots of searching the last couple days. ~Cam
