The best thing about the F6 is its ability to drive the price of the F5 down to levels where a serious amateur can afford one. As far as I can see, there is little or no improvement between the models.

I've had an F5 for 4 years now - great camera! But I can't see any reason at all to "upgrade" to the F6.

Nikon disappoints me these days, letting Canon get the jump on them at every turn ....
