The Diamondback would be stronger. Activator Solid, Rocket Core. I purchased one to go with my Rattler (same core, pearlized version of the Activator) just haven't punched it up yet due to the success I've been having with my Raw Hammer Anger. The Rattler is so underrated. However, I feel like a lot of the mid range pieces people pass up for the strongest ball on the market are underrated.
Ahhh Disco Biscuits!
