cpio VS tar and cp

Question

I just learned that cpio has three modes: copy-out, copy-in and pass-through.

I was wondering what are the advantages and disadvantages of cpio under copy-out and copy-i

Answer 1

TAR(1) is just as good as cpio() if not better. One can argue that it is , in fact, better than CPIO because it is ubiquitous and vetted. There's got to be a reason why we have tar balls everywhere.
