The articulation point (the fifth wheel) allows the tractor and trailer to pivot, meaning that turns can be made much more sharply than a single vehicle of equal length would be able to.
Weight distribution is better, as it is spread out over five (or more) axles which are spaced out from each other.
The ability to drop trailers can make for quicker turnaround times, as a driver can drop an empty trailer, and immediately hook up to a loaded trailer.
The ability to swap trailers also means that drivers aren't limited to just one trailer type - when running flatbeds for a company which had both flatbed and van trailers, I was able to drop the flatbed and pick up a van trailer if there was no flatbed freight to be found in the area I was in.
