Yes, I vape sweet flavors exclusively...my most subtle sweet flavor (and by "subtle" I mean predominately sweet, not "sweet & fruity" or "sweet & bakery") is a cotton candy by MBV and that's in my Mega now. I have MBV Sticky Bun in my Kayfun, Mad Alchemist Custard Matter in the original Nautilus (with BVC coil) and Hurricane Vapor Fog Milk (another custard) in my new Mini.
So far I am able to experience the MBV Cotton Candy very thoroughly in the Mega; I've vaped about five other sweet flavors in the Mega and since I vape on low watts I feel I am getting a great flavor from it. I have my favorite, Fog Milk, in the Mini, and granted, it is very good. I generally drip this liquid on a dual coil Igo-W so I know very well what this particular Liquid tastes like and can do. The Mini is holding its own, flavor-wise, against what I'm getting from the dripper. So points to Aspire.
However I will say that Vaping the mega at 7.0 watts is giving me more flavor and vapor than the Mini at 8.0 watts. BUT I don't want to run my mega at 8.0 watts (afraid the coils will burn up), so maybe that is another advantage to Mini.
YMMV. If I had to pick one, I'd go with the Aspire BVC coils. I just know they will endure longer than the Kanger coils. The design (aesthetically), IMO, is better in the Mega. But who gives a crap about aesthetics if you're getting a great vape?
So I think they're both great. Slight flavor advantage to the Mega, but I'm holding out final judgment to see how each performs after a month or two.
