C-C triple bonds are also pretty stable, e.g. acetylene and other alkynes. C-B bonds on the other hand... I don't recall ever coming across one before today.

Bond strength isn't necessarily a measure of bond reactivity. Triple bonds are often quite reactive, and in certain contexts they're incredibly unstable and have unusual reactivity - see "benzyne"

Are benzynes really a triple bond, though, or are they more like a double bond with a "+" charge on one carbon and a "-" charge on the other?

I mean youre not wrong but this argument can be applied to an absolute ton of chemical functionalities. I don't have time to dig up evidence but I'm sure benzyne has been characterized spectroscopically to determine. I'd imagine it as a resonance structure of a triple bond and charge separated species like you would an ylide or sulfoxide, but neither is wrong
