Different hunting scenarios will usually dictate choice of appropriate tools (read firearms). For example - if Whitetail Deer hunting will usually involve close range shooting out to 65 yards +/- then a smoothbore shotgun equipped with a rifled choke (or even with a plain choke such as IC) will serve very well - provided one has taken the time to optimize performance by matching a particular brand of slug to a particular shotgun (bbl).
Saboted slugs in rifled bbl'd shotguns will serve very well in terms of long(er) range as well as accuracy (read 100 yards +). However, due to the design those slugs will perform very poorly in smoothbores.
