[Grammar] What / Which

[Walt Whitman]

Which type / kind / sort of films do you like best: horror or detective films?
What type / kind / sort of films do you like best: horror or detective films?

Two questions:
(1) Are “type / kind / sort” usually interchangeable?
(2) Do they require “what” or “which”?

Thanks a lot.

You'll hear both "What" and "Which" at the start of these questions. I prefer "What".
In this context, type/kind/sort are interchangeable.

(Note that we don't put a space either side of a slash mark, as shown in the last sentence above.)
