Carnera is more proven against better competition, and has decent enough skills to outbox and outwork Baer
Buddy. He has enough power to knock out Carnera quite quickly. He also has quite a decent chin himself. I figure he can maul Carnera early and never let him recover.
I think Max was better and a harder puncher than his younger brother. But, lest we forget, Carnera was actually outboxing Max Baer and won the majority of the rounds (I believe) on a broken ankle.
