This is my typicall workflow when creating renderings.   For showing quick previews when someone is looking over my shoulder and asking questions > Fast Renderworks For middle of the road and while having my daily coffee > Custom Renderworks, adjust quality as needed For those almost there moments and fine light tunning > Always Renderstyles + adjust sheet resolution as needed ( 25dpi, 72dpi, 150dpi, 300dpi, 600dpi)
