Depending on what you want to do with the rifle, basically weight and shooting distance accuracy.
Heavy barrels or Bull barrels take longer to heat-up, thus maintaining good accuracy for more shots. They are also usually more consistent in the way they vibrate as a bullet passes down their length, which also helps for better accuracy. Their weight (within reason) makes it easier to hold the rifle steady. For all of these reasons, heavy barrels are generally more accurate bench/target shooting and SHTF rifles, as well as shooting varmints at a distance.
For CQB it is hard to beat a light bbl. A 16" std for a "close-in" tactical carbine.
A fluted heavy barrel is only a little heavier than a standard weight. The best of both worlds with accuracy.
