The main every-day difference is with quoting. "$*" will give you a single string, whereas "$@" will give you one string per array element.

Code:

$ star_style() { for i in "$*"; do echo "$i"; done; }
$ at_style()   { for i in "$@"; do echo "$i"; done; }
$ star_style 1 2 3
1 2 3
$ at_style 1 2 3
1
2
3
