Boy oh Boy is there a difference! Shoot it at 320 and watch your photo's EXPLODE. Its very nice film if you want the Velvia look (IMHO, its even more saturated in colours).
The only one issue I had, is with asian skin tones.. my wifes face went a little yellow/green in a couple of photos. The Kodak film lacks the fourth colour layer of the Fuji films, so there is more trade off to the colour correction.
Another film to try is Fuji 800 NPZ, its awesome too. Whilst not in the super saturated camp, its not just a boring normal look, it has what I term a "degrassi street" flavor.... a little romantic with a touch of Kodachrome...
