In what situation is it the best solution? (Or even a good solution for that matter.)
Well I'd argue that it is well suited in the environment I was in today. An old club with voids all over the place. They don't want conduit/trunking running on the surface everywhere, and it would have been impossible to install conduit/trunking in the void as a retrofit. Being able to rod T+E in the voids allows for progress to be made.
