Depends on the species you are after and whether you are keeping them. I have found that on trout hook up streamers do alot of damage to the fish. Sometimes with trout I have had the hook come thru near the eye and it could not be removed without doing alot of damage. But it may not be as big an issue with something like pike with the long mouth. It definitely does reduce hang ups though.
