I have been spending some time using the Quixel Suite to see what it can do.
Here is a BT Fibrebox made as, what will be, part of a series of street furniture.
The model is fairly low poly with the majority being used for the door locks and the hinges. The decals were taken from photos I took of the cabinet and added to the base albedo map. The normal map and AO map were created with XNormal and NDO then all added into DDO for the final detailing (including the fresh dog wee!).
All in all I think it has come out quite well :)
