Probably the toughest decision to make within the Nikon system... I've owned both, and currently have the 600TC.
For any brand outside of Nikon, I would never even consider a 400 f2.8. it's just not enough reach without a built in TC for most wildlife, and I prefer 300 f2.8s since they are much smaller and cheaper.
IMO - with either lens, you could easily sell the 800PF. Both the 400TC and 600TC + external TC's offer better IQ than the 800PF. The only advantage the 800PF has is the weight savings.
Since you already have the 70-200 + 400 4.5, I would probably go for the 600TC - assuming you can often carry all 3 lenses and then make your pick that way.
