$(sed foo) is a bashism for `sed foo` - the only difference between $(command) in bash and `command` in both bash and /bin/sh is that the backquote version can't be nested.

Consequently it's always better to avoid $() in portable shell scripts (though using it in machine specific ones is a good idea because it is several orders of magnitude easier to read.)
