The downside of Haskell is that performing mutations is more difficult than with traditional imperative or object oriented languages, as monads take some time to get used to.
That said, it's a wonderfully elegant and expressive language, and I suggest you just jump in and try it as opposed to looking for someone to convince you not to ;p. Learn you a Haskell for Great Good, and Real World Haskell are both available online, and are great resources. (written from a phone, otherwise I would provide links, though a google search should bring them up quickly)
Good Luck! moving from imperative/oo to functional style can be a mind bender, but don't let yourself get discouraged, it's still just code. :)
