The "$@" form preserves quoted arguments. This script will demonstrate:

#!/bin/bash

for i in $*
do
  echo "Arg1: $i"
done

for i in "$@"
do
  echo "Arg2: $i"
done

$ ./myscript 1 2 3 "4 5" 6

Arg1: 1
Arg1: 2
Arg1: 3
Arg1: 4
Arg1: 5
Arg1: 6
Arg2: 1
Arg2: 2
Arg2: 3
Arg2: 4 5
Arg2: 6

Note the "4 5" on the second set of args
