If I had to break something as efficiently as possible and had the option between a soft rubber mallet, a hard rubber mallet, and hammer made of metal, why would I choose either of the rubber mallets when my goal is to be as destructive as I can?

These are two very different things in terms of beybattles, rubber isn't used for destruction but is mainly used for stamina/breaking other's stamina. Hence the name "Impact" and not "Destroy" or "Breaker"

From Dictionary.com:

Impact, Noun: the striking of one thing against another; forceful contact;

The impact of the colliding cars broke the windshield.

To be fair, until TT uploads their review/advertisement video of it I assume it'll just have the generic "offensive rubber" marketing, which implies that rubber = better attack, but nothing specific as to how or why it's good.
But then again, they do seem to make a point of Wizard Rod getting knocked away in the (oddly ASMR) 15-second advertisement for Impact Drake here.

When I said Impact, I knew it made contact, the point I was making was that the rubber isn’t a straight up destroyer or breaker
