It depends on the situation, halt will stop the current script, as well as all "parent scripts", return will only stop the current script.

Eg:

Code:
alias test {
  if ($istok(return halt,$1,32)) { test $+ $1 }
  echo -a 1
}


Code:
alias testreturn {
  echo -a 1
  return
}


Code:
alias testhalt {
  echo -a 1
  halt
}


/test return - You will see that the return in the "testreturn" alias only stops that alias from running.

/test halt - You will see that the halt in the "testhalt" alias will stop that alias, but also the /test alias from running.
