should i get a programmer or tune it

just bought an 01 sierra with the 5.3 and im wondering if i am better off to get a programmer like the superchips cortex or the diablo sport, or am i better off to get a tuned ecm? not looking for huge power gains here just wanted to add that little bit more. so lets hear your opinions
