Hi Sarah,
I'm glad to help here! Taste is always going to be subjective; however, in my opinion, and the opinion of most others I have discussed this with, the Aspire Nautilus Mini does offer superior flavor to the Kanger Genitank. Outside of tanks with sub-ohm capabilities, the Aspire Nautilus Mini, produces better flavor and vapor than any other tank that I've used. I use mine every day.
Best regards,
Brad
