I have both and can make this easy. Do you want bass or do you not want bass. The Hexa has good "neutral" bass with a little added sub bass, but the mid bass slam of the Zero is the star IMO. To the point I EQ'd my Dusk sub bass to match the zero and I enjoy it more cause I found I love mid bass. It also comes down to what music you listen to. I listen to a lot of deathcore and that sort of thing, so I highly prefer the Hexa tuning cause it keeps the bass tight and I can hear everything surprisingly well. Personally, the zero is fun, but I prefer the Hexa, but I've also found I like a big of sizzle to my treble and would rather have less bass then more so, hope that helps
