There are places where its easier to get in with an artic than a rigid, and you can drag trailers around sideways, but risky to tyres, suzies, the ground and you still need space, the long wheelbase and sometimes crap steering lock on some rigids, make things a pain because the turning circle, so you end up needing to shunt around, but you will get into plenty places that an artic can’t.
Wag and drag, depending on how its setup, while longer than an artic, will get in places it has no hope of
