So, which guitar has a better sound, quality and is worth the money?

Jackson is around 300 $ cheaper, has a basswood body with maple neck (+rosewood fingerboard) and EMG 81/85 pickups.

Dean DM has a all mahogany body/top with ebony fingerboard, and Dave Mustaine Livewire pickups.

Which one should I get?

I'm aiming towards Dave Mustaine Dean because it's different than my Ibanez now (which also had basswood body and maple neck like this Jackson), but what's your opinion guys?
