concatenation should be more efficient as formatting takes 4 more 
bytecodes than concatenation, one of which is binary_format which will 
take more execution time.

However unless your application does many of those it is not worth the 
effort to choose one over the other. I almost always favor formatting as 
it is so much easier to read, maintain and extend.
