Polaroid 667 vs Fuji 3000

[Radioiron]

For those of you who've used Polaroid 667 before it was discontinued, how does Fuji 3000 compare? I've got some to use in my Graflex with a homemade back and was wondering about how the tonality and range compares. I've taken one exposure as a test and was wondering how different the original Polaroid emulsion was.
