I've never heard of the Kodak film. It should be fine since its only a 100 speed and just out of date.
The Fuji might have some fog since its a higher speed film. I'd use it anyway. If you have a bunch of it, shoot a roll at 800 and see what it looks like. Depending on how you like the results, either shoot the rest at 800, or downrate it to 640, or 400.
I *think* the Fuji should be good for most situations, including those with people. It's just going to be grainy since it's a fast film. I'm guessing here, but the Kodak is probably one of their consumer films marketed outside the USA. So its probably similar to Gold 100, in which case its a great, punchy all purpose film. I have a ton of Gold 100 and so far its been nice for everything I've used it on. The skin tones might not be as smooth and natural as Portra, but I have absolutely no qualms using it on people.
