Neither, I Render out a separate layer called Z-depth using render elements. Then i bring the two layers into a third party program and use the Z-depth as a mask to tell the Gaussian blur how much is each pixel is blurred. Its so much faster than using any of the blurs in 3ds max, Instead of rendering the scene 12 times to get the effect, The Z-depth layer doesn't not require GI, Final gather, or any lighting, materials, or anything else of that matter, only objects and the gray scale value is determined from the distance they are with the camera.
