The big win is readability, in my opinion. If you have variables or
expression intermingled with your string, it's harder to tell what the
result will be. In particular it's harder to tell which columns things will
be starting or ending on, so aligning things nicely across multiple lines is
harder.

That said, I don't think this should be part of the language. There's
already the MessageFormat class, which covers a lot of the use cases. It's
not perfect by any means, but as it's not embedded in the language syntax
there's nothing to prevent you writing a replacement.

Also (maybe) of note: Python had this feature for a long time but it's been
*removed* from the latest version of the language (3.0).
