Film is capable of producing a very keen edge, too keen, if .3um is used, but very comfortable with 1um and a paper backer.
If you are having that kind of problem, you are doing something wrong.
Neither is a King 1k slow, it is soft, but not slow. A 1k diamond plate can set a bevel but will leave a chippy edge and is not recommended as a bevel setter for a new honer.
My experience with film and the King 1k are not like yours.
