No, I am not saying that D800 has better AF. Both cameras are about equal after FW update on D800.

What I am saying is that in order to shoot a person/actor being interviewed (not posing for you) in a very low light you need to get a shutter speed of at least 1/160 and take a lot of shots to get few sharp.I would love to get more like 1/250-1/320.

OK based on what you said above and your another post below, I don't see why Nikon cameras have particular advantages in these scenes at high ISO.  Actually based on two lenses you described, Canon 70-200L/2.8 IS II is sharper than Nikon counterpart, 5DIII AF in low light w/o using assistant light, is as good as or could be slightly better than D800.  If you could afford another camera, then get Canon 300L/2.8 IS II instead of Sigma 120-300/2.8 OS, that again is better than Nikon 300G/2.8 VR.

These are not just paparazzi shots. I usually pre-focus and wait until I get some kind of expression on the face.

5DIII has 61 AF pt, 45-cross-pt among them (faster lenses have more cross-pt available to choose from) so you can select a cross-pt and 5D3 can shoot faster in burst rate.

Even a simple sudden laugh can ruin the picture. I was struggling with 5D2 and 7D. With D800 there is a lot less struggling because I can underexpose (thus getting the higher shutter speed) and bring it back without banding.

5D2 and 7D are old cameras and 7D is crop camera so not at the same level of D800.  But 5D3 is a different story.  In high ISOs, 5D3 actually has higher DR than D800.  Technically there is no difference from perspective of noises/grain between you expose correctly (on your subject, the interviewed person) at one ISO stop and you underexposed (in order to use faster shutter) and then push 2-stop back.  Canon cameras have no more banding than Nikon in high ISOs as Canon cameras have higher DR than Nikon's ones in high ISOs that confirmed in DXOMark sensor's tests.

I'd say 5D3 will handle as good as D800 in your described scenes.
