First, I don't think this is a useful place to look for answers since
it doesn't really matter to make which way you choose.

There's no difference between the two options except that if you use a
"chained link" model then conceivably you could avoid replacing the
"outer" link and just replace the "inner" link if the major so version
doesn't change.  With the libtool method you would always replace both
links.

But in reality your makefile will always replace both links anyway; it
doesn't seem useful to add the complexity needed to avoid it.

So, there's no difference.  Remember that symlinks are expanded by the
_kernel_ when you open the file; it's not possible to tell the
difference unless you go out of your way to do so by checking for
symlinks using a special system call.
