I used a few rolls 20+ years ago. It was simply wonderfull. Then I started doing my own neg processing with Unicolor K2. The results were high color saturation and contrast. Little did I know Unicolor changed K2 from when it was previously used. I thought it was the film changed to accomodate the trendy high saturation look of the time.
Too bad I made a wrong call otherwise I would have a freezer full of Ektar 25. Sorry Kodak.
Grain was really fine. I had a hard time using a grain magnifier. The colors were normal saturation and contrast.
