If you watch the episode 'Ben 10,000' from the original series, the part where Ben 10,000 changed cannonbolt to diamondhead pretty much stated diamondhead would do more damage in battle than cannonbolt. And Ben 10,000 has great knowledge over his aliens after using them over the decades so he would know what he is doing when changing cannonbolt to diamondhead.
