I found Haskell

I found the typing system in Haskell sometimes got in the way. Likewise, although Haskell has some capacity to define new language constructs, Lisp's macros are more powerful, and this provides a further degree of flexibility. I also find Haskell to be harder to read than lisp, largely because of built-in syntax and lazy evaluation. I also seem to recall haskell being pretty slow. Lisp on the other hand can be as fast or faster than C. Furthermore, with good unit testing, the sorts of errors one would catch in haskell, also get caught early on in lisp.

Paredit. You don't read the parens, you read the indentation and let the editor transform the code as you command it.

It's a trade-off between theoretical safety and ease of design. I prefer the latter, but there are people that prefer the first.
