I think a lot of it could be personality based. With C, Lisp and Forth you bash out code and run it, see if it works and then make changes. You get much faster visual feedback.

With Haskell, you need to put in a lot more up front thought. Then stuff doesn't compile and you spend ages working out why.. You can go for hours without having anything running. The cause of the errors can be quite abstract and obtuse and may seem like it is nothing to do with the actual problem you are trying to solve.

Different people just suit different styles.
