Cascadian Farms is actually owned by General Mills, who makes Cheerios. So, Purely-Os and Honey Nut Os are literally organic Cheerios. They are, to my taste (and I'm a real foodie) indistinguisable.
As for the honey and botulism, spores aren't destroyed easily by heat. Most of the honey you buy at the store is pasteurized, and it's still dangerous. (No good reason for the pasteurization - honey is totally anti-bacterial, anti-fungal and anti-viral. The spores are the only thing that can "live" in it, and that's because they're inert until they go into action.)
